Justin Bieber Tops Mentor Usher; The Karate Kid Kicks the Competition at the Kids' Choice Awards

It's not every day you get slimed by Johnny Depp (or that you beat out your mentor for a major award of the night).
Such was the case, however, at the 24^th Annual Kids' Choice Awards Saturday in Los Angeles, when the Alice in Wonderland star broke out a slime blaster while nabbing an orange blimp for Favorite Movie Actor (and Justin Bieber won the Favorite Male Singer award over his mentor Usher).
"You guys are the future," Depp said calmly to the crowd before he surprised them with a spray-down of the beloved green goop. "Take good care of us."
And there was much more sliming to come...

Kids' Choice Awards host three-peater Jack Black kicked off the awards show by driving a monster truck over two limousines, followed by a rendition of the Black Eyed Peas "I Gotta Feeling" (the band later joined him for their 50^th awards show performance "Dirty Bit").
While that performance didn't garner any of the green stuff, Russell Brand was next in line when he handed over the Favorite Animated Movie Voice award to Eddie Murphy for Shrek Forever After.
"I'm never having children!" Brand said as the kids pelted him with slime from the audience.
Then it was Heidi Klum, who was slimed in stilettos when she presented the blimp to Selena Gomez for Favorite Movie Actress (and no, Gomez didn't thank the Biebs).
So, who were the slime escapees (an apparent honor for the KCAs)?
While Miley Cyrus and Jaden Smith took home awards for Favorite Movie Actress (Last Song) and Favorite Movie (The Karate Kid ) respectively, both dodged the proverbial green bullet, as did Jaden's sister Willow, who later hit the stage to whip some serious hair.
And while the KCA's are generally all about fun and games, Justin Timberlake brought a slightly more serious note to the evening when he accepted The Big Help Award for his work with the Shriners Hospital for Children.
"I want to dedicate this to all of you very cool, very loud kids," Timberlake said. "This is your world."
