Who hasn’t had the anxiety dream, where you have to perform in front of an audience and suddenly realize you’re not wearing clothes? It wasn’t really a noticeable difference, but apparently it was a missed costume change that left Miley Cyrus performing in her underwear irl during her Milwaukee show on Sunday.

Miley's performances tend to get pretty intense - it's no wonder she forgot her outfit.

Cyrus herself reported on Twitter that because of a delay, she was forced to run out on stage without putting on her whole outfit, according to the Daily News. She was just about to perform her hit 23 and didn’t want to keep fans waiting.

Oops... Cyrus quickly apologised to her fans.
