Guess The Twiglet Limb

Whose uber-skinny limb?This lady has us agape with her teeny weeny arm.

In fact, we're rather worried it might just snap in two.

But who's the celeb behind the skeletal shocker?

Paris Hilton is the lady in question.

Paris HiltonThe blonde socialite flaunted her ultra-skinny limbs as she left a members' club in London, dressed in a figure-hugging light pink frock.

So slim is her arm, we're surprised she could even manage to support the weight of her handbag.

Is the stress of Paris' search for a new Blighty BFF taking its toll on Paris' fig?

Or is this simply her natural body outline?
