Little Miss Miley Cyrus walked out on stage in nothing but her bra and panties during her Milwaukee stop for Bangerz. She performed “23” in just her underwear because this naughty popstar didn’t make her quick change. Miley went on Twitter to explain: “not a new outfit for 23,” she said, “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 :(”
