Katy Perry got a little more than she bargained for when she invited a fan onstage at the Rock In Rio festival in Brazil.

Her famous lyrics “I kissed a girl and I liked it” came back to bite her in the ass – almost literally when she was confronted by a wild chick from the crowd.

We’re still not quite sure what the girl’s name is – and neither is Katy – but one thing’s for sure: she was hot as the Amazon for the pop queen.

In footage of the incident posted on social media, Katy tells the crowd: “She’s kissing my neck! … Woah! that’s my boob!”

The whole clip is hilarious and Katy even slaps the fan’s ass as she walks off stage – to which the ‘Katy Cat’ replies by giving the singer one final grope.
