Justin Timberlake vowed to "break the slime barrier" at Saturday's 20th Annual Nickelodeon Kids' Choice Awards – and the show's host sure did deliver the green goo.
Timberlake, who won the award for favorite male singer, was slimed both at the beginning and end of the show.
During the opening number, Timberlake, dressed in a tuxedo and an orange scarf, sang: "You'll never get a drop of slime on old J.T." – but was soon covered with it.
Other stars who got drenched with the green stuff included Mandy Moore, Tobey Maguire, Steve Carell, Vince Vaughn, Chris Tucker, and Jackie Chan. Even Nicole Kidman got slightly slimed when she accepted the award for the animated movie Happy Feet. (The actress, who voiced a character in the film, was there on behalf of the film's director, George Miller.)
The show, which featured performances by Gwen Stefani and Maroon 5, also featured a 23-story bungee jump into a giant vat of green slime.
Early in raucous show, Charlotte's Web star Dakota Fanning won for favorite female movie star and the Black Eyed Peas won for favorite musical group.
"I consider all of you my friends!" said Fanning, who was presented with the award by Blades of Glory stars Will Ferrell and John Heder.
Other awards went to Ben Stiller, who took home the night's top honor, the Wannabe Award, Adam Sandler for favorite male film actor and American Idol for favorite the TV show. Idol judges Randy Jackson and Paula Abdul were on hand to accept the award.
Sandler, who won for favorite male movie star in 2003 and 2005 as well, accepted the award while speaking in his Happy Gilmore and thanked the crowd "for not making fun of me for talking like this every speech I do."
As for the biggest burp – Timberlake gave up the title after he was challenged by the entire 12,000 person crowd to a burp-off. With the help of some special effects, everyone in the at Pauley Pavilion burped at once, and defeated the singer.
At the end of the show, Timberlake, with the help of Vince Vaughn, used a "detonator" to release a giant surge of slime that came up through the floor, spraying much of the audience and the actors.
Awards are determined by kids who vote to pick the winners. Approximately 40 million votes were cast this year, according to Nickelodeon.
