In Reese Witherspoon's new movie, "Vanity Fair," you'll see the star like you've never before. In the film, Witherspoon plays a scheming social climber in the 1800's, who's not afraid to use her sexuality to move up in the world. "Extra" hooked up with the star to get her take on the film and so much more.

"Extra:" So do your kids even know that you're famous?

Witherspoon: Oh sure, oh yeah.

E: Outside of your kids, what are you most proud of?

W: My marriage, (Witherspoon is married to actor Ryan Phillippe) marriage isn't easy, and it's something I work very hard at.

E: In "Vanity Fair" you play Becky Sharp, and for the first time we see you as a really sexual woman. Thoughts?

W: Oh, I know. Ouch.

E: In Vanity Fair magazine, you said you'd never wear a bikini again in a movie. Why are you so firm on that?

W: Oh, I don't know. I was having a mood. What I was saying was I had to work out so hard to do the bikini in "Legally Blonde." I get awkward and embarrassed.

E: You just had your second child, so is your secret really doing 200 sit-ups a day?

W: (laughing) Is that what I do? I do run a lot. I run, and I exercise and lift weights.

E: So do you want more kids?

W: I would love more kids, but I can't even imagine. I live bedtime to bedtime right now, and I can't imagine having another bedtime.

E: What would your dream role be?

W: Co-starring with Meryl Streep. She's pretty amazing.
