Sienna nervous about acting alongside Knightley

Washington (ANI): British actress Sienna Miller has revealed that she was "nervous" about acting with super-skinny Keira Knightley because she had been forced to gain some pounds for the role. Miller, who co-stars with Knightley in forthcoming movie The Edge of Love, was asked to put on weight for the film, which tells the story of Welsh poet Dylan Thomas.

And Miller confesses that having to gain weight for the film made her anxious, as she feared her trim co-star would emphasise her added bulk. "I was actually pretty nervous about acting alongside Keira because my part required me to put on weight," Contactmusic quoted her, as saying.

"I stuffed my face for the months we were in production. I had huge fry-up breakfasts, pasties for lunch and lots of toasties (toasted sandwiches). "Then, I had to face seeing myself alongside Keira, who is the most beautiful woman in the world," she added.
