Ananova:

Sienna Miller says she'd love a fuller figure but work on the remake of Alfie is so hectic she's losing her boobs.

The 21-year-old, who co-stars with new love Jude Law, told the Mirror: "I've lost weight and my boobs have gone, they're just clinging on for dear life.

"I used to have boobs, honestly I did. I went to put on a bra this morning and I don't need one.

"I think it's the excitement, adrenaline and stress. I don't normally look like a twig and I do eat like a pig, but the weight has just dropped off me.

"I want tits and an arse. I would love to be voluptuous, but I've just always been skinny. I think it would be wonderful to have curves."

Sienna, who is half-American, half-South African and attended an English boarding school, never intended to become involved with a fellow actor.

But she is cautiously optimistic about her new relationship with Jude, 30, who is divorced from mother-of-four Sadie Frost.

She said: "I'm nervous because I've seen what happens to relationships when you're doing this."
