Girls Aloud performed to a packed 02 crowd on Saturday as part of their Ten tour, but Kimberley Walsh seemed to be stealing all the attention - for all the wrong reasons.
At one point during the show, she slipped into a glittery monochrome playsuit, which was unfortunately fitted in a way that it created 'material nipples' on her bust.
And it didn't go unnoticed by the audience. One fan wrote on Twitter: "Currently mesmerised by @KimberleyJWalsh 's amazing prominent nipples. She'll have your eye out. #GirlsAloudTenTour."
Madonna, eat your heart out...
