Kimberley Walsh wardrobe malfunction on stage at O2 Arena in London

Kimberley Walsh suffered an embarrassing wardrobe malfunction on stage at the O2 Arena in London on Friday night.

Girls Aloud‘s Kimberley Walsh  seemed unaware of her appearance as she stood on the stage in the cut out monochrome playsuit

The singer’s chest certainly caught the eye of members of the audience and one tweeted that he was “mesmerized”.

The fan posted: “Currently mesmerized by @KimberleyJWalsh ‘s amazing prominent nipples. She’ll have your eye out. #GirlsAloudTenTour.”

While Kimberley Walsh might have looked chilly she posted a message to Twitter about how hot the show was.

The singer wrote: “What can I say London……….you were on fire tonight I could actual feel your heat #tentour.”

At one point during the show, the group had a little sit down together on some glowing white stairs – reserving their energy during a ballad maybe as their shows are known to be super-energetic.

During the upbeat numbers, star of the show Cheryl looked picture perfect as she strutted around the stage in her clinging corset and blinging costume.

The Geordie lass seemed to throw all her aggression into her following moves, a look of intense determination to get through this number.

And the girls said London was their best venue yet – with hundreds of screaming fans obviously in agreement.
