Katy Perry's Rock in Rio 2015 set is making waves on the blogosphere for reasons other than her hit catalogue, and the footage is simply glorious.  

In the middle of her Prismatic World Tour set in Rio de Janeiro, Brazil on Monday night (September 28), the pop titan invited one lucky fan to the stage for an impromptu meet and greet sesh. We're going to put money down that Katy did not expect everything that followed. Not only did the fan get up close with the California Gurl, but she also went in for the neck. We're talking a few kisses on the neck.

The next three-and-a-half minutes were filled with some not-so-successful lessons in Portuguese, selfies with the pop star and even more touchy touchy action. Thankfully, Katy dealt with it all in humor, and we have to admit that that sort of reaction from such a power celebrity is quite refreshing.

Watch all the action unfold in the clip above!
