Katy Perry got more than she bargained for when she invited a fan on stage during her performance at Rock in Rio festival in Rio de Janeiro, Brazil, on Monday.

The female fan was a little overzealous as she hugged, kissed and groped Perry, much to the singer’s amusement.

“She’s kissing my neck!” Perry told the crowd. “I might need that water back.”

The fan kept wrapping her arms around Perry, prompting the singer to proclaim, “I think she’s rolling.”

Whether the fan was actually rolling onMolly (aka MDMA), which is a controlled substance in Brazil, is unclear, but it seems like Perry might be on to something.
