A newly-single Katy Perry was all smiles at Nickelodeon's 26th Annual Kids' Choice Awards Saturday night in Los Angeles, where the pop star took home an award for Favorite Female Singer. Not even John Mayer can end this girl's winning streak.

Pitbull and Christina Aguilera opened the award show by performing "Feel This Moment" (check it out below), which ended with Aguilera pushing a button that dropped green slime on Pitbull. His tourmate Ke$ha also performed, teasing "We R Who We R" and then launching into “C’Mon.” Watch here

Other winners include One Direction, who nabbed Favorite Music Group and Favorite Song (“What Makes You Beautiful”), and Justin Bieber, who was named Favorite Male Singer.
