Jim Carrey got slimed and feathered. Britney Spears and Justin Timberlake put on brave faces and laughed together — though clearly kept their distance. And Jennifer Love Hewitt and Jackie Chan were honored for what they do best: kick butt.

So went the 16th annual Nickelodeon Kids’ Choice Awards, which aired Saturday from their traditional Southern California base, Santa Monica Airport’s Barker Hangar. For the seventh consecutive year, Rosie O’Donnell served as host.

Timberlake did more than just show up and present an award (which was all Spears did). He followed Kelly Clarkson and David Hasselhoff by stepping to the microphone to do what those two couldn’t: He belched on cue.

Clarkson, her “American Idol” costar of last season, Justin Guarini, and Kelly Rowland of Destiny’s Child even downed root beer in the hopes of letting out a crowd-pleasing belch. No such luck.

Timberlake’s contribution, however, was so loud that he didn’t need the microphone to make himself heard — and he won the title of burping champ from those voting on

Carrey, meanwhile, wasn’t simply content to get slimed by green goo and feathers. He reacted by picking up the slime hose and letting O’Donnell have a little goo herself, along with some members of the audience.

“What does it feel like?” Carrey said backstage, according to USA Today. “It feels like love, man, slimy-gooey love.”

Brad Pitt and Michelle Pfeiffer (who remained reasonably clean) presented the favorite female movie star award to Amanda Bynes for “Big Fat Liar,” while Adam Sandler claimed the fave male movie star prize for “Mr. Deeds.” The kids’ favorite movie was “Austin Powers in Goldmember.”

Meanwhile, Hewitt and Chan were picked as favorite female and male butt kicker, respectively, for “The Tuxedo.” And music awards went to B2K, Nelly, Ashanti, No Doubt and Avril Lavigne.
