Miley Cyrus turned Madison Square Garden into her own holiday hoedown Friday night, closing #Z100JingleBall as only Miley could.
Check out the photos from her rockin' (and raunchy!) performance, complete with a butt slap from a Christmas tree, grabbing said Christmas tree's giant booty, spanking one of her tiny dancers and turning up the stage with her passionate performance.
She's just being Miley...
