Anne Hathaway looks chic and sassy as she poses in her underwear for the cover of the January 2013 issue of Glamour.

Anne Hathaway lost 25 pounds her role for "Les Misérables." And now the actress can't stop talking about how fit she feels and doesn't shy away from showing off her lean body.

After her rather sophisticated and elegant look on the cover of Vogue, the actress sports a more sassy and sporty look for the January issue of Glamour in her underwear. 

The actress also revealed that she had to literally starve herself to look the part in the upcoming film.

"I had to be obsessive about it; the idea was to look near death," Hathaway told Vogue. "Looking back on the whole experience, it was definitely a little nuts. It was definitely a break with reality, but I think that's who Fantine is anyway.

"I like to fight for a job. You feel like you've emerged from the scrap, and you're like, 'OK, this one's mine. Did it. Done,'" she said.

Hathaway, who switched to a vegan diet while training for "The Dark Knight Rises," has really embraced the plant-based eating plan.

"I don't go the soy-meat route; I have a really plant-based diet," she said. "So I wind up cooking at home a lot. Kale is amazing. Spelt [a kind of wheat] pasta is amazing. I can't do the white-flour stuff. It makes me really ill."

The actress also revealed that she was flattered when President Obama called her the "best thing" in "The Dark Knight Rises."

"I'm a blusher, and just being inches from him, I went scarlet from the tips of my toes to the tops of my ears," said the actress.

The actress revealed that she can't wait to become a mom.

"Oh, my God. I want to be a mother, and I anticipate loving my children quite fiercely. I think about it all the time, though it's a silly thing to think about because the kind of mother I'll be depends on the kind of children I have. I can't wait to meet them."

For now, she feels as if she's right where she's meant to be. "I'd feel a little silly and overly dramatic to say that this feels like destiny. But to have this come full circle in such a spectacular way-it's making me very happy... OK, it feels a little like destiny."
