Last night, Nickelodeon's 25th Annual Kids' Choice Awards was held at Galen Center in Los Angeles. We love this award show not only because we get to see our favorite celebs get slimed and to hear the hilarious celebrity pranks, but also because of the colorful fashion that dominates the red carpet! Like always, the red (or should we say orange) carpet was plentiful with pop stars posing for pictures in playful and colorful outfits! The red carpet was all about the famous faces including Katy Perry, Selena Gomez and Heidi Klum. Click on the pictures to check out some highlights from the arrivals last night!
