Watch Katy Perry's Onstage Standoff With a Fan She Thinks Is Rolling at Rock in Rio

Katy then attempts to learn a little Portuguese -- but mostly just learns that pizza in Portuguese is “pizza” -- before the two, naturally, must take a selfie together. Commence more kissing.

For the record, here’s the selfie they took:

Cuuute.

Anyway, speaking of concerts, remember when Taylor Swift threw some Left Shark shade at Katy Perry onstage?
