Katy Perry kissed by hands-on super fan after inviting her on stage during concert in Rio de Janeiro

"She isn't the first, and she won't be the last," the singer admitted

Katy Perry was kissed by an excited fan after inviting her on stage during the singer’s appearance at Rock and Rio festival in Brazil.

A video posted online shows Perry helping the girl on stage and complimenting her outfit before realising the super-fan might be under the influence of something.

“She’s kissing my neck!” Perry tells the crowd.

“I think I might need my water back, we need some water,” she says to someone offstage as the girl, allegedly called Rayane, rests her head on Perry’s chest.

They make a joke about Perry being unable to pronounce the girls name, before she appears to grab Perry’s breast and causes her to yelp in alarm.

Throughout the video, the girl continues to kiss Perry’s face, neck and hands.

“I think she’s rolling,” Perry jokes.

According to Gigwise, the girl has defended her actions on Twitter. Translated from Portugese, she denies being drunk, and claims her behavior was due to 'exhaustion' having travelled to Rio from Perry's previous gig in Sao Paulo.

Perry attempts to engage the hands-on fan in small talk, and even takes a selfie with her, but the girl refuses to stop kissing her. Perry eventually gives up and ushers her off the stage, but not before slapping her behind.

Perry then attempts to make light of the whole subject, saying “She isn’t the first, and she won’t be the last.”
