(TMZ) - Miley Cyrus likes big butts (and she cannot lie) so of course she would hop up on stage and join a group karaoke rendition of the Sir Mix-a-Lot classic "Baby Got Back."
Miley took a Bangerz Tour break and stopped into Cat's Meow, a karaoke joint in New Orleans.
A few girls were up on stage doing "Baby Got Back" when Miley jumped up on stage to join them ... and immediately turned around and showed off the goods.
