Katy Perry had an odd encounter with a fan during her recent concert in Rio.

It Looks Like Katy Perry & John Mayer Are Back On!

After bringing the fan on stage during her show earlier this week, Perry was bombarded with questionable grabs and a few neck kisses, which led her to believe the fan, who was wearing a smiley-face bra at the time, may have been rolling.

"The 'Pearl' singer performed at Rock in Rio over the weekend and wanted to welcome to the stage a Brazilian fan," Entertainment Tonight reported on Tuesday. "So, she picked 'the girl with the smiley face t***ies' and unwittingly entered into a four-minute PDA standoff with a girl who was, maybe, according to Katy Perry, possibly, rolling."

During Perry's standoff with the fan, a woman named Rayane, the two women posed for an awkward selfie, and Perry told staff they needed water. Perry also suggested the woman was on drugs, telling the crowd, "I think she's rolling!"

Throughout her encounter with the pop star, Rayane embraced Perry, and at one point, Perry called her out for touching her breast.
