Despite a running gag where Mark Wahlberg declared himself "unslimeable," the 2014 Kids' Choice Awards host found himself covered in that unmistakeable green goo on Saturday night. The 42-year-old Transformers: Age of Extinction star hosted the annual Nickelodeon event at the Galen Center in Los Angeles, and couldn't escape the show's signature bit. With a little help from Kevin Hart, the actor's own children got in on the act. #slimeable #KCA pic.twitter.com/KNBiqIf8xf— Mark Wahlberg (@mark_wahlberg) March 30, 2014 But he wasn't the only celebrity to partake in the sloppy tradition -- Kaley Cuoco, Pharrell Williams, magician David Blaine, Austin Mahone and Cody Simpson also got slimed. Hunger Games: Catching Fire took home several of the night's big awards, including Favorite Movie and Favorite Movie Actress for Jennifer Lawrence. Adam Sander won Favorite Movie Actor, while Frozen picked up Favorite Animated movie.
