Oops! Rita Ora Suffers Major Nipple Slip in London

Rita Ora said 'R.I.P.' to a bra and unintentionally flashed her lady lumps in front of concertgoers at her Red Bull Culture Clash show in London on Wednesday (Nov. 7).

The 'Shine Ya Light' singer hit the stage in an all-white motorcycle outfit with matching helmet and gave Londoners quite a titillating show. Apparently, while Rita was performing, her zipper slowly came undone and -- Pop! -- her right boobie made a guest appearance.

The Roc Nation songbird went on Twitter to apologize to her fans for her embarrassing mishap. "Yes, its true. I got straight off a moterbike from O2 to Wembley I didn't have time to change and then all of a sudden the zip got lower [and] lower. I rushed on stage and pop! It happened, f---! Sorry guys," she tweeted. She also added, "(How embarrassing) apologized! Dispite that, amazing show! :) LOL."

Don't feel so bad, Rita -- it has happened to the best of them. From Keri Hilson to Jennifer Lopez to Nicki Minaj, you're not truly a pop diva unless you're tatas make a grand entrance.

Thanks for the mammaries, Rita!
