“I kissed a girl..” BUT I did NOT like it!

Katy Perry is always full of surprises even while at the Rock in Rio festival!

A fan of the gorgeous Katy Perry went on stage and completely surprised the singer. Perry invited the fan on stage who wore a smiley face bra as she then began to grope the singer and give kisses on her neck and cheek.

The young woman did not stop grabbing Perry for several minutes onstage, at times appearing to make the singer rather uncomfortable, though she remained poised and joked around with the female.

Perry sent her off the stage with a pat on the butt, where she then went back onstage to grab the singer’s behind then left.

Check out the video of the incident:
