London, Sep 19 : Keira Knightley has worried fans with her extremely thin frame. However, she insists that she in one of the “largest actresses” in tinsel town.

In a recent interview, the ‘Pirates of the Caribbean’ actress bizarrely claimed that she was ‘twice the size’ of most of the women in Hollywood.

"I'm twice the size, height and everything else of most of the girls going in to see the director for a part,” the Mirror quoted her, as saying.

Meanwhile, the British actress has attributed her success in Hollywood to her svelte body.

The Atonement star, who battled the world's obsession with her body image last year, asserted that she owes much of her fame to her slim figure.

"I mean I'm an actress and it's a tool, after all. It's pretty much all I've got. I've got whatever's in my head, my face and my voice and then there's my body, and that's it. And I do trade on that, of course I do," she said. (With inputs from ANI)
