Sometimes a woman has to make sacrifices for fashion, and that may include foregoing panties to make a look complete.

Jennifer Lopez wore a Kaufmanfranco sheer paneled backless column gown to the Las Vegas premiere of "Parker," and it appears that she skipped wearing underwear to avoid those pesky pantylines.

The 43-year-old singer/actress looked stunning in the cut-out illusion gown just one day after wearing an elegant white dress to the New York City premiere of the film.

Jennifer Lopez attended the premiere of "Parker" at The MoMa in New York City on Wednesday. The actress looked amazing in a strapless white peplum Lanvin dress with matching pumps.

Beyonce's purported lip syncing at President Obama's inauguration on Monday made headlines yesterday, and singers Jennifer Lopez and LeAnn Rimes gave their two cents during Tuesday night talk shows.

Rimes supported the R&B star, telling Jimmy Kimmel: "There are times when people will ask you to do it and they will not let you do it unless you do it because they want control over what happens."

On "The Daily Show," Lopez said certain venues pre-record things because of "terrible slapback."  She explained, "All performers do have to do it at some point."

Of course, that doesn't explain why...

Jennifer Lopez knows how to make a statement. We spotted the singer/actress out and about in New York City this afternoon following her appearance on "Good Morning America."

The 43-year-old star looked sexy in a leather and leopard-print outfit with high heel boots. Without a doubt, the middle-aged star still has it going on.

Lopez recently told People magazine: "I've never had Botox or any of those things. [But] when I need to, maybe I will. I don't know how I'm gonna feel. I reserve the right to not know right now. And I don't judge anybody who does it."

Jennifer Lopez sits down with PEOPLE in this week's issue for an exclusive interview and photo shoot in Beverly Hills where she opens up about what she's learned about love. The pop icon, 43, gets personal about her difficult split with Marc Anthony, from whom she separated in July 2011 after a seven-year marriage (their divorce is not yet final), raising her twins Max and Emme, making movies, the perils of dating a much younger man, and more. Below are highlights from Lopez's interview with PEOPLE's deputy managing editor, Peter Castro.

On Learning from Her Mistakes
"I'm not a young girl ...

Jennifer Lopez's split from husband Marc Anthony took its toll on the set of new action movie Parker - she was so depressed there were mornings she couldn't function or raise a smile.

The couple separated in July, 2011 after seven years of marriage, and Lopez admits she didn't have time to mourn the break-up because she was preparing to face off with Jason Statham in the new crime thriller, which started shooting a month later.

In the film, the On the Floor hit-maker plays a real estate agent ironically recovering from a divorce, and while Lopez had no trouble relating to her character,...

Sunday night was one of the of the biggest events in Hollywood - the 2013 Golden Globes Awards. Red, white and black were some of the more popular choices on the red carpet, with stars such as Zooey Deschanel, Jennifer Garner, Claire Danes, Marion Cotillard and Jennifer Lawrence opting for crimson gowns.

Hosts Amy Poehler and Tina Fey wore black and white, and Eva Longoria looked very leggy in a black gown with a slit up the thigh. Salma Hayek also stunned in a strapless black dress that showed off her curvy figure. Rachel Weisz wore black with a sheer polka dot skirt and her best accessor...

On February 9, Justin Bieber will become the latest star to simultaneously host Saturday Night Live and perform as the episode's musical act. However, he's far from the first.

The Rolling Stones are the only entire band to provide comedy and music on the show. Everyone but Bill Hyman was involved in the sketch comedy way back in 1978. Last season, Mick Jagger returned to both host and sing, giving him the honor of being the star with the longest gap in time between appearances.

Have you ever had, or witnessed, a bra-tastrophe – when something goes totally wrong with a bra? It's just another thing that women have to manage while getting dressed every day. Celebrities try to avoid wardrobe malfunctions, but they happen all too often, and unfortunately the public can't keep their eyes off the trainwrecks.

Jennifer Lopez shows her sexy curves and wears some fancy footwear in the February 2013 issue of Harper's Bazaar magazine.

The 43-year-old singer is fresh off a world tour, has a new movie (Parker) out January 25 and is getting ready to start work on her 10th album.

She could have easily traded all that for another season of American Idol (she banked over $35 million for the two seasons she did the show), but that's not who she is.

"I'm not a judge for a living, I'm a singer. I'm a dancer. I'm a performer. I'm an actress. That's what I'm supposed to be doing," she says. "It makes me a be...

Celebrities wear many provocative gowns, but there are few that the public remember as well as the Versace dress with plunging neckline that Jennifer Lopez wore to the Grammy Awards in 2000.

Fashion lover Lopez has confessed that she still owns the iconic piece but only looks at it once in a while.

She told Harper's Bazaar, "I have that at home. The other day, my housekeeper put it on a mannequin in my spa, where I get my hair and make-up done. She sent me a picture. She was like, 'You like this dress?' Um, yeah, but I don't know if I like it out in the house!"

2012 saw its fair share of celebrities showing off their sexy curves in bikinis at the beach (and one-piece suits as well), but which stars were the sexiest of all?

Some were snapped by the paps, while others discovered the magic of Instagram and shared photos nearly every time they went, minimally clothed for some sun, sand & surf.

Stars like Kim Kardashian and Rihanna seemed to post their sexy shots the most, while supermodel Bar Refaeli shared lots of photos with her fans.

Britney Spears got her bod back to its rockin' old form; while Stephanie Seymour, 44, and Daisy Fuentes, 46, prov...

Singer/actress Jennifer Lopez donned shorts and sneakers to take part in a charity soccer match in Puerto Rico on Saturday.

The "Jenny From The Block" singer and her tour dancers, including boyfriend Casper Smart, played against a team made up of local artists including reggae duo Wisin & Yandel at the Hiram Bithorn Stadium in San Juan.

The game came just hours before Lopez played the last night of her Dance Again World Tour in the country.

Pop star Jennifer Lopez has been hit with a bizarre new lawsuit.

Everette Draughn has accused the Dance Again hitmaker's Spike TV reality show, Big Easy Justice, of falsely labelling him as a grand theft auto suspect in an episode that aired in April.

Now the 19 year old has filed legal papers in Louisiana, where the series is shot, for unspecified damages over claims the program bosses ruined his reputation, caused him injuries, and cost him his job, according to TMZ.com.

Big Easy Justice, which follows a team of bounty hunters as they track down criminals in New Orleans, is produced by...

Jennifer Lopez's representative has played down fresh rumours the superstar is planning a secret Christmas wedding to her boyfriend Casper Smart after they were photographed shopping for diamond rings in Australia.

The couple, which began dating last year following Lopez's split from husband Marc Anthony, was snapped browsing for sparklers at top jewellery store Tiffany & Co. in Perth on Thursday, prompting speculation the singer/actress was set to head to the altar for the fourth time.

However, the On the Floor hitmaker's spokesperson insists that is not the case, telling the New York ...

Jennifer Lopez is under fire for firing one of her maids for allegedly asking J-Lo for an autograph. Now, Lopez says the maid was cut loose for not following security rules.

The German maid was quoted by German mag Bild as saying, "I cleaned on [sic] her floor... And I am an incredibly big fan so I took all my courage and rang the bell to get an autograph. But I was rejected by two assistants at the door.

"A day later, the cleaning company that employed me at the hotel called and said that Ms Lopez had complained... I was fired right there on the phone. Because of an autograph."

Jennifer Lopez has spoken out to dismiss allegations she played a part in the dismissal of a hotel maid who was reportedly fired for asking for an autograph, calling the story "hurtful."

Cleaner Pray Dodaj claims she was fired after she knocked on the star's room door to get a signature during Lopez's stay at the Melia Dusseldorf hotel in Dusseldorf, Germany last week.

She told German newspaper Bild, "I am an incredibly big fan so I took all my courage and rang the bell to get an autograph. But I was rejected by two assistants at the door. A day later the cleaning company that employed m...

Jennifer Lopez attended the UNESCO charity gala at the Maritim hotel in Dusseldorf, Germany, on Saturday. The singer/actress looked incredible in an over-the-shoulder black lace dress.

She kept her whispy, honey brown hair down and wore sparkling dangling earrings. Jennifer perfected the look with bright pink lipstick.

Jennifer has been keeping busy during her European concert tour. Earlier in the month she had a wardrobe malfunction while performing in Bologna, Italy. Her nipple popped out of her silver sequined Zuhair Murad bodysuit.

It's a celebrity's worst nightmare - a wardrobe malfunction (although we're pretty sure some of them plan it). The phrase skyrocketed in popularity in 2004 after Janet Jackson performed at the Super Bowl with Justin Timberlake and he tore open her top, exposing her right breast while singing, "Gonna have you naked by the end of this song."

Savvy stars do whatever they can to avoid embarrassing skin-revealing incidents, but inevitably a dress seam rips, a skirt blows up, or a nipple peeks out.

Jennifer Lopez had an unfortunate wardrobe malfunction while performing in Bologna, Italy, last week.

The pop star's right nipple popped out of her silver sequined Zuhair Murad bodysuit while she was on stage on Thursday. It could happen to anyone - particularly if they wear barely there bodysuits.

A "lucky" photographer was able to catch the incident on his camera, which is featured on the following page. For those watching from the audience, it must have been a blink-or-you'll-miss-it moment.

This type of things has happened before. The singer/actress had a similar issue at this year'...

Jennifer Lopez still keeps in touch with her ex-fiancé Ben Affleck, eight years after their highly-publicized split.

The Pearl Harbor star proposed to Lopez after a whirlwind romance a decade ago, but the love affair broke down abruptly in 2004, as the couple was planning its wedding.

The former American Idol judge eventually moved on and married her now ex-husband Marc Anthony, while Affleck later walked down the aisle with actress Jennifer Garner.

Lopez had twins with Anthony, while Affleck and Garner are now parents to two girls and a boy, who was born earlier this year.

Jennifer Lopez's new TV venture has been targeted by conservative campaigners over its focus on a lesbian couple raising children.

The singer/actress is an executive producer of new small screen series The Fosters with her Nuyorican Productions company, and the show stars The West Wing's Teri Polo and Rescue Me's Sherri Saum.

However, its focus on same-sex parents raising kids together has angered activists at campaign group One Million Moms, who have urged members to complain to the network behind the show, ABC's Family Channel.

The post reads, "ABC Family has approved a series pilot...

A representative for Jennifer Lopez has brushed off speculation the superstar is engaged to her dancer beau Casper Smart.

The three-times wed "On The Floor" hitmaker sparked a new round of rumors suggesting she was heading to the altar once again after she was spotted sporting a large diamond on her ring finger while in Paris, France earlier this week.

However, Lopez's spokesperson has now dismissed the reports, telling Eonline.com, "Jennifer is not engaged."

It's the second time in four months Lopez and Smart have faced wedding claims - the singer/actress had to shoot down allegations s...

Some stars have huge egos and think the world revolves around them.

Their narcissistic ways and self-importance are often laughable and at times frightening.

So which stars are always finding themselves giving pats on the back to... themselves all the time? Read on...

Kanye West once said "I am the number-one human being in music"; and told Entertainment Weekly that he's "too busy writing history to read it." Quotes like these cemented his status as one of the biggest egos in showbiz. He's launched his own fragrance, brand of shoes and energy drinks; and he even had the cojones to cut ...

Jennifer Lopez was spotted with a HUGE rock on her left ring finger Tuesday when she took her daughter Emme to her first fashion show in Paris during the city's Fashion Week on Tuesday.

J. Lo's new hardware ocaused quite a stir, setting off rumors for the fourth time this year that she's gotten either engaged or married to boyfriend Casper Smart. In March fashion designer Roberto Cavalli's twitter page was hacked, and it featured a tweet that J. Lo had asked him to creat a new wedding dress for her. Then the always reputable Star magazine reported that the couple were secretly wed on a tri...

Jennifer Lopez, her daughter Emme Maribel Muniz and Casper Smart went to Paris Fashion Week on Tuesday. The actress/singer looked amazing in a low-cut short lace frock, while her daughter was adorable in a pink dress, dainty socks, and bright shoes. The four-year-old carried a butterfly-shaped purse.

Lopez later tweeted, "Thank You @karllagerfeld for inviting Emme and me to her first fashion show! http://t.co/PId1kvYd."

Lopez's son, Max, didn't attend. She is currently dating choreographer Smart and is filming a behind-the-scenes documentary about her life and career.

Jennifer Lopez didn't want to split up with ex-husband Marc Anthony. The singer/actress is family oriented and it was a difficult decision for her to seek a divorce. The couple wed in 2004 and split in summer 2011.

On new daytime talk show "Katie," Lopez explained, "You never want to break up a family. That wasn't my dream. My dream was for us to always be together. But things don't work out, and you feel like it’s the better choice. If I didn’t feel it was the better choice, I wouldn’t have done it, you know?"

Despite the divorce, Lopez says she and Anthony have found common ground to r...

We spotted Jennifer Lopez smiling for photographers while leaving the Greenwich Hotel in New York City yesterday.

The singer wore a tight jumpsuit that a normal-sized woman would have trouble wearing because the fit and fabric don't appear to be very forgiving.

Lopez recently flew to New York from Miami, Florida, where she shot scenes for a new documentary about her life. She also took some time off before resuming her concert tour in Europe, Asia and Australia.

The pop star stars in the upcoming film "Parker" opposite Jason Statham about a thief who lives by a code of honor that includ...

Jennifer Lopez showed off her sexy curves in Miami again, wearing a black bikini and spending time in the pool with twins Max and Emme on Saturday before having some alone time with boyfriend Casper Smart.

Jennifer looked a bit camera-shy during her time with Smart; 18-years her junior; appearing to hide herself from watching eyes by wearing her towel into and out of the water with help from her boy-toy.

J. Lo's son Max reportedly squirted a security guard with water, according to PacificCoastNews.com.
