LOS ANGELES -- Green slime spewed furiously at the Kids' Choice Awards on Saturday, where "Twilight Saga" star Kristen Stewart and British boy band One Direction won two awards apiece.
Stewart, 22, escaped the slime but plunged her hands into the green goo, saying she "felt like I have finally found my kindergartner self," as she accepted trophies for movie actress and favorite female butt kicker.
Organizers said more than 350 million votes were cast online in more than 20 categories, spanning film, television, books, music and sport for the stunt-filled annual award show on youth channel Nickelodeon.
Hosted by "Transformers" actor Josh Duhamel, who is married to singer Fergie, the show in Los Angeles featured performances by Pitbull and Christina Aguilera, as well as Ke$ha.
Johnny Depp and Katy Perry accepted orange blimp-shaped trophies for favorite female singer and movie actor respectively and both stars had words of wisdom for the audience of kids and young teens.
"This is such a cool award ... stay safe, stay in school, don't do drugs," Perry told them. Depp said he was "truly honored and humbled. Thank you for what you are, which is the future."
Selena Gomez, 20, the ex-girlfriend of pop star Justin Bieber, took the female TV actress award for her Disney Channel series "Wizards of Waverly Place," even though the show came to an end more than a year ago.
Bieber, who is on tour in Europe, was voted favorite male singer and was among several stars who did not make it to accept their award in person
No-shows included One Direction, who are also on tour and who won for favorite music group and song for "What Makes You Beautiful," "X Factor" judge Simon Cowell (favorite villain), and Ross Lynch, 17, who was named favorite TV actor for Disney Channel's pop star series "Austin & Ally."
Sandra Bullock, Neil Patrick Harris, Duhamel, Pitbull, Nick Cannon, Dwayne "The Rock" Johnson and dozens of audience members got covered in slime gushing out from water cannons, presenter's podiums, ceilings, and even the tail of a fake gymnastic horse.
Other awards went to Nickelodeon's "Victorious" for top TV show, "The Hunger Games" for favorite movie, "Wreck-It Ralph" for top animated movie, and race car driver Danica Patrick and basketball player LeBron James for top athletes.
The Kids Choice Awards will be broadcast around the world in more than 25 languages, Nickelodeon said.
