While performing at Rock in Rio, a huge music festival in Rio de Janeiro, Katy Perry brought an enthusiastic fan on stage but didn’t quite know what she was getting herself into…

The fan (whose name Katy couldn’t understand) would not stop kissing and touching her, which, as you can see from the video, made the singer pretty uncomfortable. She even jokes the fan might be “rolling” and she needed water.

But Perry handled it with grace. As the fan was leaving the stage, she pats her on the butt saying, “You’re not my first, and you won’t be my last.”
