Sienna 'Jenna' Miller

Jenna Jameson wants Sienna Miller to play her in the movie of her life.

The porn star previously singled out Scarlett Johansson to play her in a biopic, but has now said she would be happy if Sienna was cast in the role.

Jenna, 33, said: "I would love Scarlett Johansson to play me. Sienna Miller would be great too. But I also think Rachel McAdams is amazing."

The busty blonde - who has retired from adult films to focus on running her $30 million-a-year ClubJenna empire, the biopic, a comic book and a clothing line - had her breast implants removed earlier this month, and feels more confident without them.

Jenna - who underwent three hours of surgery on August 1 to reduce her breasts from a D-cup to a C-cup - told Us Weekly magazine: "When I had implants, I felt uncomfortable. I would be shy at the beach. I know it sounds funny, but I'd wear high-necked clothes - unless I was at an adult film convention. So I thought, 'Why don't I be who I am and get my real ones back?'

"Even for women with naturally large boobs, getting a reduction is so freeing. I feel like I can stand up straighter. And before, when I jogged, I had to hold my boobs. I looked like I was molesting myself!

"I'm ecstatic about the reduction. The first thing I did when I got home was open my bra. I wasn't supposed to but I did. I was so happy, I cried. It was like looking into the mirror when I was 17.

"I had my surgery while my boyfriend (33-year-old ultimate fighter Tito Ortiz) was entertaining troops in Iraq. He was so excited, he said, 'I'm coming home to brand new boobies.' "
