It was a big surprise for all teen audiences of the 8th Annual Teen Choice Awards that Britney Spears appeared in a pink cleavage-baring dress which shown her heavily pregnancy and introduced her hubby onstage.

"This show has been very good to me and my career over the years. And I'm hoping that it will be as good to our next performer," she said. "Please give a big welcome to my man, Kevin Federline."

Kevin prowled and jumped around the stage, surrounded by young dancers, enthusiastically performed his single "Lose Control." Unfortunately he lost out on his nomination at the Male Red Carpet Fashion Icon ceremony to Nick Lachey.

Also performing in the event are Breakout Female Musician winner Rihanna and V Cast Music winner Nelly Furtado with her single "Promiscuous." Jessica Simpson and comedian Dane Cook were the hosts of this event which aired live on Fox from the Gibson Amphitheater in Universal City.

Handsome duo Orlando Bloom and Johnny Depp, who each snagged an award for their swashbuckling parts in "Pirates of the Caribbean: Dead Man's Chest," which picked up seven honors had made the girls screamed. Other winners including Reese Witherspoon, who won "Best Actress in a Drama" for her role in "Walk the Line," and Jessica Alba for the "Hottie Female" and "Female Red Carpet Fashion Icon" category.
