Justin Bieber, Kristen Stewart and Taylor Lautner are all winners at Nickelodeon’s Kids’ Choice Awards. but it’s all about the slime

The Kids' Choice Awards are primetime for slime, and the 25th edition of Nickelodeon's annual celebration for kids didn't disappoint. Kristen Stewart, Taylor Lautner and Justin Bieber supplied the star power and the green goo made for the fun.

Halle Berry was the first to be covered (left), but that was just the beginning. She was joined by "Twilight" star Lautner (below, who won the Kids Choice Blimp for favorite "buttkicker"), "Glee" star Chris Colfer and male singer winner Bieber, who was utterly drenched along with host Will Smith at the end of the show.

Smith started the show with a digitally-animated skydive from Nickelodeon's trademark blimp. He was then hoisted from the rafters to the stage of the Galen Center at the USC, where thousands of glow-stick waving fans — including first lady Michelle Obama — cheered

Obama later presented "the big help" award for charity work to Taylor Swift. "I am freaking out," the pop start said.

Winners are chosen from voting online. Selena Gomez won for both favorite TV actress and female singer. Adam Sandler took home the award for favorite movie actor. And Katy Perry, shortly after performing, was given the award for favorite voice in an animated movie.

"The only reason why I'm still here today — and remember this — is because I've never grown up!" Perry told the young audience.

Unlike other awards show, there was not much thanking of agents.

"This is, like, the coolest award show ever," said "Twilight" star Stewart, accepting the honor for favorite movie actress.

Nickelodeon's "Victorious" won best TV show. Jake Short, star of the Disney Channel's "A.N.T. Farm," won best TV actor.

The show ended with — what else? — a mega-sliming of host Smith and Bieber.
