Academy Award-winning actress and doting mother, Nicole Kidman, credits her post-baby curves with nabbing her a role in the star-studded cast of Nine. Kidman tells Entertainment Tonight Canada, “[I had] big boobs because I was breast feeding–I was perfect for it. I wouldn’t get cast now.”

The Australian-born movie star clarifies to the Ladies’ Home Journal, “They’re not very big, my boobs, so they just became normal size. I loved it!” She adds, “I felt very Woman.”

And according to Kidman, the ladies on the set of Nine–Marion Cotillard, Kate Hudson, Penelope Cruz and Fergie–kept the estrogen levels on the set very high. Nicole explains, “Kate had her son there, and Penelope Cruz and Fergie were like, ‘I can’t wait to have a baby.’ We’re all women’s women.” In fact, Nicole will also be a man’s woman, in a manner of speaking.
