Britney Spears kicked off her Piece of Me residency at Planet Hollywood in Las Vegas on Friday night and performed for an audience of mega fans that included Miley Cyrus and Katy Perry.
It may not have been Cyrus' music, but pop's new bad girl was nodding her head like yeah and moving her hips like yeah. Cyrus, who had a front row seat between Spears' mother Lynne and sister Jamie Lynn, couldn't stand still during the show, waving her hands and bopping to the beat like a giddy teenager.
Spears played a gracious hostess, tweeting her thanks to Miley and gamely winking to Cyrus' new single "Adore You."

It's clear that Cyrus even knows all of the words. No twerking here: just good clean fun from a couple of Disney alums.
