While singing “Adore You” during her Bangerz Tour concert in Los Angeles on Saturday, Miley Cyrus, sparkling from head to toe in a black cat suit and serious heels, came down from the stage and locked lips with Katy Perry, who was sitting in the front row.

The kiss lasted just a second but seemed to catch Perry by surprise. She backed away quickly and put her hand over her mouth. Cyrus also seemed to gasp. I think Miley slipped her the tongue.
