A drunk (and handsy) Katy Perry fan made things VERY awkward

by

Katy Perry is definitely no wallflower, but even she was a little taken aback when she was greeted on stage by a very over-zealous fan last weekend.

The singer was performing at Rock in Rio on Sunday, and this video of her on-stage encounter with a superfan started doing the rounds last night.

As usual, Katy picked a fan from the crowd to bring on stage in front of an audience of tens of thousands, but she got a little more than she bargained for when she pulled Brazil native Rayane out of the front row.

Confused, handsy and definitely more than drunk… this was one reveller that probably should have been taken home.

"We need some water," Katy joked at the girl began kissing her neck and (accidentally, we think) grabbing her boob.

"She's rollin'!"

Dressed in a smiley face crop top and shorts, Rayanne certainly looked the part of a Katy super-fan, and she revealed she'd even been to her Sao Paolo gig just days beforehand.

In huge praise to Katy, the singer remained totally professional and friendly throughout – she might as well have been chatting to Rayane at a house party, not on stage in front of a sold-out crowd.

The video is worth a watch… even if you take it as a warning of what NOT to do at your next concert.
