Beyoncé Knowles took center stage at the Billboard Awards in Las Vegas tonight. She performed her new single, "Run the World (Girls)," in a sexy sparkling barely there dress before being presented with the Millennium Award. The honor recognizes Beyoncé's music and her involvement in The Survivor Foundation's humanitarian work. The singer was not only celebrated with a statue, but also with a video tribute that included clips from First Lady Michelle Obama, Lady Gaga, Stevie Wonder, and her mom Tina. Beyoncé kept it in the family when accepting the award and gave a shout-out to her husband Jay-Z in her speech.

Britney Spears and Rihanna took the stage at the MGM Grand Arena to open the Billboard Awards in Las Vegas tonight. The duo performed Rihanna's hit "S&M" and shared a sexy almost kiss in between belting out the lyrics. It was Britney's first appearance of the night, since she's also set to take the microphone with Nicki Minaj. Rihanna's up for 18 awards, including Top Artist, Top Female Artist, and Top R&B Artist while Nicki was nominated for four. Britney isn't up for any prizes at the event, though now that the show is returning after a five-year break, she should be able to snag a few in 2012 for her work on Femme Fatale.

Maddox, Zahara, Pax, and Shiloh Jolie-Pitt had a special outing to the premiere of Kung Fu Panda 2 in LA today. Brad Pitt and Angelina Jolie walked the red carpet, greeted fans, and posed for pictures without their little ones, who were waiting inside to watch the film. The whole Jolie-Pitt crew is back on the West Coast after traveling to France for the Cannes Film Festival, where Angelina talked about how much her children loved the animated movie during her press day. Their trip overseas wasn't just about Angelina though, since Brad also premiered his new project, The Tree of Life. The screening was met with mixed reviews, but apparently made an impression on the judges, since it took home the festival's top prize, the Golden Palm award.

Kung Fu Panda 2 stars Angelina Jolie, Jack Black, Danny McBride, Seth Rogen, and Lucy Liu joined fans this morning at LA's Grauman's Chinese Theater for the stateside premiere of their animated movie. Brad Pitt was front and center alongside his beautiful partner, Angelina, who stepped out in another high slitted dress. The couple were just in Cannes last week on behalf of her Panda and Brad's Tree of Life. Brad did lots of press for his Terrence Malick film, which won the film festival's top prize, speaking about their hectic family life, his religious beliefs, and revealing he'd like to work with Angelina again.
