Selena Gomez Kid's Choice Awards Nickelodeon

Will Smith hosted the 25th annual Nickelodeon Kids' Choice Awards tonight, and not only was there plenty of green slime, but some of our fav celebs walked away with the top prizes!

Selena Gomez won for both Favorite TV Actress and Favorite Female Singer, and her beau Justin Bieber snagged the award for Favorite Male Singer. Selena showed quite a bit of skin in this Dolce & Gabbana dress, and while it's a pretty floral print, it seems a bit er, skimpy for younger audience, doesn't it? Then again, she has been in a bikini filming Spring Breakers for the past few weeks, so maybe that influenced her fashion this evening...

Kristin Stewart won for Favorite Movie Actress while her Twilight co-star Taylor Lautner went home with the prize for Best Butt Kicker, and Katy Perry was given the award for Favorite Voice From An Animated Movie for her work on The Smurfs.
