Pretty sure no one was expecting Katy Perry to kiss THIS girl. Katy decided to check out Miley's Bangerz tour stop at L.A.'s Staples Center. While Miley was singing "Adore You' she climbed down the stage and motioned Katy over then just stuck her lips out for kiss!

Except it looks like Miley was a little more into it than Katy! Watch for the tongue-prep head turn! Ahaha!
