Katy Perry performed at the Rock in Rio festival in Rio de Janeiro last weekend when she invited one of her Katy Cats to join her onstage, when things took a weird turn.

The fan began by hugging Katy which quickly progressed to several kisses on the cheek and moved on to her neck, where she stayed for an uncomfortably long time.

"We might need that water back. We need some water," Perry told the crowd, adding, "I think she's rolling!"

The fan then began to grope Perry, eventually grabbing one of her breasts before she eventually left the stage, but Katy took it like a champ! Here's video.
