Katy Perry burst onto the scene in 2008 when she famously sang that she kissed a girl and she liked it, but a recent incident might have changed the singer's mind. Earlier this week, Perry performed at Brazil's Rock in Rio festival, and she took the opportunity to engage with her fans, even inviting one on stage. After briefly introducing herself , the fan immediately began to grab Katy, and then proceeded to touch and kiss her.

This all went on for a couple of minutes before a very poised Katy joked "She's rolling." After several selfies, Katy prompted her off stage with a pat on the butt with the fan returning for one last grab before she left. "You're not my first, and you won't be my last," said Katy.
