Kimberley Walsh shows off her curves in a sexy sheer dress at book party

She's in the best shape of her life after Strictly Come Dancing and the Girls Aloud farewell tour.

So you can't blame Kimberley Walsh for wanting to show off her toned figure in a revealing dress.

Arriving at a publishing dinner at the BAFTA headquarters in London on Thursday night, the pop star left little to the imagination in the black mini dress with sheer panels.

The tanned singer, 31, had to go braless in the risque dress, which perhaps was a bit too racy for a publishing do.

Ahead of the bash, she tweeted: 'On my way to BAFTA for @headlinepg book event.'

Kimberley was attending a sales conference dinner by publishers Headline, who will publish her autobiography later this year.

The deal was announced last month by Headline's deputy publishing director Sarah Emsley, who said: 'Girls Aloud were a true British success story and I couldn't be more thrilled that Kimberley has chosen this moment to tell her story.

'Her book is sure to be packed full of the warmth and laughter that makes Kimberley such a national treasure and reading it will feel like curling up on the sofa for a gossip with an old friend.'

Social butterfly Kimberley has been out nearly every night for the past week.
