Beyonce is expecting her first baby with husband Jay-Z. The pop superstar stunned photographers, fans and the press at the MTV Video Music Awards in Los Angeles on Sunday night by cradling her stomach and showing off a baby bump as she posed for red carpet photos in a flowing red gown. 

The gossip sites and blogs went into overdrive as photos of the magical moment shot around the globe via the Internet and her representative confirmed to, "I'm happy to say it's true."

And Beyonce spoke of her pregnancy happiness as she began her joyful and energetic performance of Love On Top during the ceremony, telling the audience at the Nokia Theatre, "I want you to stand up on your feet, I want you to to feel the love that's growing inside of me."

As the track ended, Beyonce dropped her microphone to the floor, unbuttoned her shimmering purple jacket and rubbed her baby belly through high-waisted black trousers, laughing uncontrollably.

Cameras at the Nokia immediately shot to delighted rapper Jay-Z in the front row, who soaked up the applause with his pregnant wife.

Following Beyonce's baby reveal, several stars took to Twitter to congratulate the star and her husband.

Beyonce's former Destiny's Child bandmate LeToya Luckett was among the first celebrities to send congratulations to the pop superstar. She tweeted, "WOW!! In tears!! Congrat's BEY & JAY!", while Jordin Sparks added, "Omg Bey is pregnant. I just squealed!!!"

Pregnant Spice Girls star Melanie Brown also took a moment to offer her thoughts, tweeting, "I love the fact Beyonce just announced she is pregnant, on her own terms, girlpower, love her!!!"

Glee actress Jenna Ushkowitz declared, "Beyonce - Preggo and still in Heels.. #respect."

It was ladies night at the MTV Video Music Awards on Sunday as Katy Perry, Britney Spears and Lady Gaga took home two honors apiece.

Lady Gaga left many onlookers puzzled by refusing to come out of character as her foul-mouthed male alter-ego Jo Calderone for the entire ceremony - even accepting her Best Female Video award as him, and Russell Brand served up a brutally honest tribute to tragic star Amy Winehouse, revealing he once wrote her off as a "crazy" woman who wandered around their native London stinking of "the booze" until he heard her sing.

His wife Perry, who had 10 videos up for prizes, took home two, including the Video of the Year for Firework, but she lost the Best Pop Video honor to Spears, who also landed the Michael Jackson Video Vanguard Award.
