Hilary Duff: Happy With Body Image, Mike Comrie

While her ex, Joel Madden, preps for a new baby with Nicole Richie, singer Hilary Duff is delaying her own plans to start a family. She's 20.

"I'm definitely not ready to get married," Duff tells Cosmopolitan in its January issue, which features the adorable signer-actress on the cover.

"I think a reason that people in this business get married young is that they feel like everything comes to them sooner in life. It's normal to be like, 'Okay, what's next?'"

Hilary Duff is quite cute. And quite grounded for her age.

Having famously dated Good Charlotte's Madden for 18 months - before they broke up a year ago - Duff is currently dating NHL player Mike Comrie.

Her sister, Haylie Duff, approves of the pairing. Which is good news for Mike Comrie. Those two are so close, you don't stand a chance if Haylie's not a fan!

On the heels of this week's controversy about body image - people now for some reason think Jennifer Love Hewitt nude isn't that hot because she put on a few pounds or something - Hilary Duff said that as a scrutinized starlet herself, she has fretted about her weight in the past, but doesn't sweat it any longer.

"You lose happiness when that's all you think about," Duff said. "There was a time, a year and a half ago, when I was pretty obsessed with my body and my weight, but I'm better not stressing about my body all the time... It's not attractive when girls get super-skinny. Guys don't like it. Girls don't like you as much."

You go, Hilary! Duff will be tackling her first serious movie role, in War, Inc., next year. This year she released her latest CD, Dignity, in April.
