The provocative Miley Cyrus -- who recently locked lips with both Katy Perry and labelmate Brooke Candy -- tongue-kissed a front-row fan during her Bangerz Tour stop in Las Vegas on Saturday, March 1. And what happens in Vegas doesn't always stay in Vegas, especially when caught on film.

During her performance of 'Adore You,' Miley walked to the edge of the stage and began making out with a blonde female fan. The intense kiss lasted for several seconds, and the audience couldn't get enough, cheering and screaming at the surprise makeout sesh. After ending the kiss, Miley immediately wiped her mouth and face with her arms -- but it wasn't in disgust. She took to Twitter to better explain why she cleaned herself up after the smooch:

 

Makes perfect sense. After all, if she's willing to make out with a fan (and put other fans' thongs in her mouth), it would be pretty shocking if she felt like she needed to wipe off the kiss!
