Miley Cyrus Performs In Her Undies After Missing Costume Change

Whatever, it's nothing we haven't seen before!

Miley Cyrus performed in Milwaukee, Wisconsin on Sunday night, and while she usually wears this sparkly underwear set with a pair of red chaps, something happened and Miley wasn't able to put together her outfit in time.

“not a new outfit for 23," Miley tweeted. "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 :( Never happened to me before. But I love my fans as much as they love me! I couldn’t miss 23 ... Show must go on :(”

She can't be that upset about it -- not only does her body look great, but this isn't that dramatically different from the complete look...
