It looks like Miley Cyrus is trying to kiss as many fans as she can while on her Bangerz tour.

The pint-sized pop star gave a female fan a very passionate smooch at her Las Vegas concert on March 1, while singing her ballad Adore You.

Kneeling down and leaning into the audience, Miley and the mystery girl kissed for a good few seconds as fans cheered on. Miley then stood up and wiped her mouth (classy), but explained her actions later on Twitter.

"I wasn't wiping of your kiss pretty girl just your dark lipstick that was all over my face. thanks for coming to the show mystery babe x," she tweeted.

Ooooohhhh.... So risque!
