No costume? No problem!
Miley Cyrus is certainly no stranger to being scantily clad in concert, but believe it or not, the 21-year-old singer pop star didn't intend to step out in nothing but her unmentionables to perform the song "23" during a show in Milwaukee, Wis., on Sunday evening.
But the gal did just that, and later took to Twitter to explain exactly what happened.
"Not a new outfit for 23. I didn't make my quick change and I couldn't not come out for the song so I just had to run out in my undies," Cyrus wrote.
Two nights earlier, a fully clothed Cyrus also got people talking (again) when she decided to bury her face in dancer Amazon Ashley's ample cleavage during a Bangerz tour stop in Illinois.
Along with a shot of Cyrus preparing to smack her butt, of course.
