Miley Cyrus and her "Bangerz" tour rolled through the Staples Center in Los Angeles and Katy Perry was in the front row, and when Miley spotted her she crawled off stage to go in for a smooch.

Miley actually tried to slip Katy some toungue... when Katy shut that make-out sesh down, Miley's reaction was priceless!

Chatting with the hosts of the Australian show "Sunrise" during an appearance this past Tuesday, Katy recalled what happened after Miley motioned to her to come close for a KissCam-broadcast smooch during "I Adore You" that night.

"I just walked up to her to give her like a friendly girly kiss, you know, as girls do, and then she like tried to move her head and go deeper and I pulled away," she said, (via E!). "God knows where that tongue has been," she added. "We don't know! That tongue is so infamous!"
