Johnny Depp and Kristen Stewart avoided slime -- mostly -- while picking up orange blimp-shaped trophies at the Kids Choice Awards on Saturday.
The "Dark Shadows" star won as favorite movie actor at the 26th annual awards extravaganza, while Stewart was selected as favorite movie actress (for "The Twilight Saga: Breaking Dawn - Part 2") and female butt-kicker (for "Snow White and the Huntsman").
"Dude, I was too much of a coward to accept this," she said embracing the slime slathered on the podium at the University of Southern California's Galen Center.
Pitbull and Christina Aguilera kicked off the show with their duet "Feel This Moment." The pair was joined by young backup dancers resembling the smooth-headed rapper and blonde diva. At the end of the performance, Aguilera smashed a button, covering Pitbull and the dancers in the show's signature green goo.
That was just the beginning of the celebrity sliming -- in one of his first acts as show host, "Transformers" star Josh Duhamel dumped the goop on Los Angeles Lakers player Dwight Howard.
"I guess that's what we call a slime dunk!" Duhamel said.
Sandra Bullock and Neil Patrick Harris caught a wave of the green stuff after a magic trick from the "How I Met Your Mother" star went awry.
Dwayne "The Rock" Johnson, who picked up the trophy for male butt-kicker, blasted a sumo-suited Nick Cannon and Duhamel with the goo. The first few rows of the audience were also doused.
Duhamel said a record-breaking 350 million votes had been cast for this year's viewer-voted ceremony, which honors kids' favorites in film, music, sports and TV.
Other winners included "Victorious" as favorite TV show, Katy Perry as favorite female singer, Adam Sandler as favorite voice from an animated movie for "Hotel Transylvania," race car driver Danica Patrick as favorite female athlete, LeBron James as favorite male athlete and "The Hunger Games" as favorite movie and book.
"Always be nice to your parents," Sandler told the crowd of screaming kids while accepting his awards. "Always be nice to your teachers."
