Katy Pery -- groped N Kisssed .... by Lucky Fema

Katy Perry Has Personal Encounter With 'Rolling' Fan - "She's kissing my neck!"

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), is unclear,
but it seems like Perry might be on to something.
