In a new interview with Vogue magazine, Katy Perry discusses her broken marriage to Russell Brand and her on/again, off/again romance with John Mayer.

The July cover girl explains that she hasn't spoken to her ex-husband in over a year and a half. They wed in India in 2010.

"He's a very smart man, and I was in love with him when I married him. Let's just say I haven't heard from him since he texted me saying he was divorcing me December 31, 2011," she explained.

Perry, 28, partially blames their split on her success. "At first when I met him he wanted an equal, and I think a lot of times...

Russell Brand is obstinate he was faithful to his ex-wife Katy Perry as he is always "diligently monogamous" when he is in a relationship.

The British comedian became known as a serial womanizer before he gave up dating and settled down with Perry in 2010. Nevertheless, the couple's marriage didn't last long, and they were divorced last year.

Now, the 38 year-old actor has open up to insist he didn't do anything to compromise his union, and actually enjoys staying faithful to one woman.

He tells Britain's Esquire magazine, "When I'm in a relationship I'm diligently monogamous and stic...

It was a who's who of celebrities at the "PUNK: Chaos to Couture" Costume Institute Gala at The Metropolitan in New York City on Monday night.

Some stars took the word "costume" very literally, dressing up like punks, teasing their hair, and laying the make-up on heavy. Other celebs opted for more traditional ball gowns.

Metropolitan Museum of Art Director and CEO Thomas P. Campbell explained the punk theme: "Punk's signature mixing of references was fueled by artistic developm...

Katy Perry's preacher father Keith Hudson references his daughter's fame during his Sunday sermons -- referring to her as the "devil child."

The pop star's father also claims that he ends up crying while watching Katy in concert, according to Britain's The Sun, because the fans are worshipping her instead of God.

It's Fashion Fail Time! That means we take a break from letting you know how good all of your favorite stars look to show the other side of fashion: the fails!

Hopefully, Katy Perry found this "gem" of a dress at a flea market, because it's at least two decades out of date. Either that, or Perry has signed on to represent a new line of screen-less phones and... Spearmint gum?

I have no problems with kilts, even if Alan Cumming's has a very odd, almost computer-like pattern. But we will never, I repeat, NEVER condone dress shirts with the arms cut off.

What's the first thing you think of when Katy Perry, Jennifer Love Hewitt, Christina Hendricks, Halle Berry or Kate Upton is mentioned?

Right, "boobs."

Thanks to magazines like Maxim, Esquire, Cosmopolitan, GQ and Playboy -- to name just a handful -- celebrity breastesses are constantly shoved in our faces.

Others are obviously real (Katy Perry), while some are obviously fake (Mariah Carey).

But in the end it doesn't really matter if they look glorious.
