In addition to being in the front row while Cyrus was singing the ballad "Adore You," Katy got the very special VIP treatment when Miley bent down into the expensive seats in the middle of the song and planted a big kiss on Perry's mouth.
"I just kissed a girl and I really liked it a lot," Miley said after the smooch. She later posted a picture of their not-so-private moment.
Before they even touched lips, Perry was psyched to be at the show. She wrote earlier in the evening, "I hope @MileyCyrus sings 'Breakout' or 'The Climb' tonight."

Afterwards, they both seemed a bit shocked that it even happened.
