Katy Perry got more than she bargained for when she invited an excited fan onstage in Brazil as the girl began to kiss her neck and touch her butt.
The Firework hitmaker was performing at the Rock in Rio Festival in Rio de Janeiro on Sunday when she invited an audience member, thought to be called Rayane, onto the stage.
The fan wrapped her arms around the singer's neck and began smooching her, and Perry told the audience, "She's kissing my neck!"
Perry made a variety of shocked faces as Rayane clutched her tightly, rested her head on the star's breasts and repeatedly kissed her hand.
The Roar star eventually eased away from her admirer, and as Rayane was about to leave the stage, Katy slapped her bottom.
