Katy Perry brought her Katy Perry–ness to Brazil's Rock in Rio on Sunday; memories were made. Perhaps not completely comfortable ones.

Perry invited a fan onstage—a woman either inebriated on substances or simply on the drug we call "being starstuck"—and proceeded to spend several increasingly touchy-feely minutes with her. The fan dealt Katy a startling amount of neck-kisses; she also leaned in exceptionally close for some full-on mouth-to-ear whispers. Possibly necessary to communicate over a billion screaming fans, but still.  

Perry's early reaction before getting a little more comfortable with her bud in the smiley-face bra: "Okay, hold on!" Followed by a few instances of, "I think she's rolling!"

Perry seemed equally bemused and alarmed, but she wound up keeping her emotional fan onstage for three-and-a-half minutes. Closing out, they gave love-pats to each other's butts, and Katy threw her selfie buddy a salute as she descended back into the audience. 

"You're not my first," Katy shouted, "and you won't be my last." Hit NME to see it go down.
