M is declaring Sunday, March 29th the most fun day of the entire year. After all, it's the day of the 2014 Kids' Choice Awards, when all of our favorite celebs win awards and get SLIMED!
From Katy Perry getting slimed right in the face to Justin Bieber's hilarious reaction to the green goo, there have been so many amazing moments that involved both celebs and slime. Check out 19 hilarious (and super messy) times stars got slimed with Nickelodeon's signature green gunk by clicking through the gallery above!
GIVEAWAY: We're so excited for the KCAs this weekend that we're giving away a Nickelodeon Kids' Choice Awards Mad Libs box set! (It's the perfect game to play at a KCAs viewing party with all your BFFs!)
UPDATE: This contest is now closed.
