Cyrus was singing "Adore You" when she walked onto the cat walk and leaned over the stage for a girl-on-girl moment with Perry.
Afterward, Miley exclaimed, "I just kissed a girl and I really liked it a lot," referencing Katy's popular song.
Of course, this was not the only sexual stunt Miley pulled Saturday night. There was also an abundant amount of crotch-grabbing, twerking, grinding on teddy bears, and she even rode out on a hot dog.
