Nicole Kidman worked on her new film to prove there's more to life than motherhood.

The actress - who gave birth to Sunday Rose, her first child with husband Keith Urban in July 2008 -accepted her role in 'Nine' immediately because she couldn't wait to get back to work.

She explained: "I'd just given birth, so I was like, 'OK, I'm still a woman - I want to do this film! And I do have a life other than simply feeding this baby.' I think when you give birth you get itchy to get back to work and you want to feel life still goes on."

Despite having only recently given birth when she made the movie, Nicole admitted she thinks she looks "very sexy" in the star-studded blockbuster - which also stars Daniel Day-Lewis, Penelope Cruz, Dame Judi Dench, Marion Cotillard, Sophia Loren and Kate Hudson.

The 42-year-old beauty explained to GQ magazine: "As it revolves around one man's view of all the women in his life, it's undoubtedly done from a male perspective - we all look, well, very sexy! Apart from the mother. But then, that's played by Sophia Loren. And who wouldn't want Sophia Loren to play their mother?

"There's an awful lot of Oscar winners. That's why we hope the film is good! Although, with more of us in the movie, the blame can be spread more evenly..."
