Famous for its merciless sliming of Hollywood's biggest stars, the Nickelodeon Kids' Choice Awards saw Sandra Bullock and Neil Patrick Harris among its targets at last night's awards show.
The pair got gunged shortly before presenting Twilight star Kristen Stewart with the award for Favourite Movie Actress.
Stewart, 22, managed to avoid splattering the slime on her blue Osman dress but did get her hands covered in gunge as she accepted her blimp-shaped honour.
Winners are chosen by young adults across the US, who vote for their favourite stars online.
Hosted by Transformers star Josh Duhamel at University of Southern California's Galen Center, this year's event attracted a record-breaking 350 million votes.
Favourite Movie Actor Johnny Depp paid tribute to the young audience telling them "Thank you for being you, you're the future".
Adam Sandler, awarded Favourite Voice from an Animated Movie, dispensed some words of wisdom when he collected his award:
