Katy Perry Was Kissed by a Girl – Over and Over Again – Watch Katy Hilariously Deal With an Eager Fan [VIDEO]

"I think she's rolling!"

Katy Perry was performing at Rock in Rio this past weekend and she invited a fan on stage who probably had too much to drink and things got weird.

The girl wouldn’t stop whispering in Perry's ear, and rubbing... hugging... kissing Perry's neck (does that make me jealous, a little).

Katy handled it the most hilarious way and just played along... for a while.

"PIZZA!"... "That's English"
