Katy Perry went through a surprising experience while on stage during her Rock in Rio performance on Sunday, Sept. 27.

The "I Kissed a Girl" singer invited one of her exuberant fans, which she called "the girl with the smiley face t*tt*es," up to join her on stage, although once the fan was up there she became a bit much to handle, according to Time.

The Brazilian girl, who is supposedly named Rayane and known on social media as #Raiaiaia, donned a smiley face bra and black shorts and a yellow and black mask. As she hopped up to the stage to meet Perry, she immediately bombarded the singer with a huge hug and a kiss.

The pair's meet-and-greet went on for about four minutes with Perry commenting on how she thought the girl might be "rolling," meaning she thought she may be tripping on a drug like ecstasy. From that point on Perry seemed concerned about the girl and said, "We need some water!"

Throughout the whole ordeal, the "California Gurls" singer seemed to nervously laugh at the situation but remained poised and even agreed to take a selfie with the girl. After they snapped the photo the fan lightly guides Perry's face in to give her another smooch. During this time Perry also attempts to learn some Portuguese, but only learns that pizza in Portuguese is "pizza."

The selfie of Perry and her crazed fan is now all over social media. Several memes have also been created showing the interactions between the fan and Perry at the concert.

As Perry sent Rayane off the stage she gave her a pat on the butt, which led the girl to reach back for one last grab of the singer before she returned safely to her place on the floor.

"You're not my first and you won't be my last," Perry said.
