Helen Flanagan Flashes Her Bum In See-Through Dress As She Leaves FHM Party (PICTURES)

Helen Flanagan has already claimed she's got the best boobs in the world, and on Tuesday night, she tried to stake her claim on having the best bum too.

The very cheeky star - famed for flashing her famous cleavage - was letting her derrière steal some of the limelight for a change as she showed it off in a very see-through bondage-style dress.

Cheeky! Helen Flanagan

Following a party at London's Whisky Mist, Helen shunned the well-established 'how-to-get-into-a-taxi-in-front-of-the-paps' protocols to give them something to take pictures of.

The bash was held by FHM in Helen's honour, to celebrate her becoming the covergirl of the new issue of the magazine.

She was previously named the UK's sexiest woman in their readers' poll earlier this year - a title which she's obviously keen to retain with antics like this.
