Pitbull and Christina Aguilera kicked off the 26th annual Kids’ Choice Awards at the USC Galen Center in Los Angeles and slime fest with their duet Feel This Moment.

And at the end of the performance, Christina Aguilera pushed a button, covering Pitbull and the dancers in the show’s signature green gunge.

Selena Gomez returned to her roots to be crowned Favourite TV Actress at this year’s Nickelodeon Kids’ Choice Awards.

And she was in good company, as winning big beside her were two modern day celebrity heroines, Kristen Stewart and Katy Perry.

Kristen Stewart looked happy and full of fun on Saturday when she accepted the award for Favourite Movie Actress, vindication indeed that she’s still a fan favourite.

“Twilight fans have been the best ever. So thanks guys for honoring me in this way,” said Kristen Stewart.

Kristen Stewart – who is often accused of being pofaced and miserable – even jumped into a sliming with Sandra Bullock and Neil Patrick Harris – when she wasn’t required to face in the indignity, her cute short suit never quite recovered.

“I love the kids,” Katy Perry told the audience after accepting her gong for Favourite Female singer.

“I think it’s the coolest award. I love you kids. Stay in school and stay safe.”

Ke$ha was also among the performers, changing out of her blue suit and hat into a fur coat, tiny black shorts and yellow top as she sang her song C’Mon.

Other winners at the viewer-voted ceremony honoring kids’ favorites in film, music, sports and TV included Adam Sandler as Favourite Voice from an Animated Movie for Hotel Transylvania, race car driver Danica Patrick as Favourite Female Athlete and The Hunger Games as Favourite Movie and Book.

Johnny Depp made a surprise performance after scooping the Favourite Movie actor gong for his role in Dark Shadows.

“I’m truly honored and humbled to get this award,” he told the audience.

“You’re the future.”

Dwayne “The Rock” Johnson also got the chance to push the slime button, managing to cover Nick Cannon and Josh Duhumel in goop after accepting his award for Best Male Buttkicker.

Despite Miami Heat star LeBron James accepting the Favourite Male Athlete award via video link, fan favorite Justin Bieber did not appear to even record a filmed “thank you” for the Favourite Male Singer award.

Presenters on the show included Pretty Little Liars star Lucy Hale, Jessica Alba, Kevin Hart.

Josh Duhamel said a record-breaking 350 million votes had been cast for the show.
