The 23-year-old Latina flashes her curves in the film adaptation of the cult comic, which also stars Bruce Willis, and she admits she found the prospect all too daunting - until she looked at Knowles.
She says, "I get self-conscious, but you have to just embrace it and go with it.
"I was so nervous during Sin City because I play a stripper. I wore chaps and little underwear. My butt cheeks were hanging out! It was so embarrassing.
"I remember being in my underwear in my hotel room, trying to get comfortable (with my Sin City role). Beyonce's Baby Boy video kept coming on MTV, and all she had on was a short little thing, and she's grooving around and she has this gorgeous womanly body.
"I was like, 'All right, if she can do it, I can do it.' I'm by no means a Gwyneth Paltrow or JENNIFER ANISTON - I'm not one of those women with a really thin body. I have body fat.
"I am (practically) naked in every movie I do. It's horrible. But I always get inspired by other actresses who embrace their curves."01/03/2005 09:32
