Kids Choice Awards: The winners

Los Angeles - Kristen Stewart and One Direction were the big winners at the Nickelodeon Kids' Choice Awards on Saturday.

At the annual ceremony in Los Angeles, the boy band took home the prizes for Favourite Music Group and Favourite Song (What Makes You Beautiful).

The 22-year-old actress picked up two awards as she was named both Favourite Female Buttkicker for her title role in Snow White and the Huntsman, and Favourite Movie Actress (as Bella Swan in The Twilight Saga: Breaking Dawn - Part 2).

Before presenting Kristen with the latter, Sandra Bullock and Neil Patrick Harris kept up the tradition of celebrities getting slimed, while rapper Pitbull and basketball star Dwight Howard were also subject to the show's signature stunt.

The award's host Josh Duhamel joked after Dwight's sliming: "I guess that's what we call a slime dunk!"
