Heidi Klum Covers Page Six

Model mom Heidi Klum strikes a sultry pose on the cover of the new issue of Page Six magazine.

The German-born beauty, who is expecting her fourth child this fall, talked to the magazine about gaining - and losing - the baby weight.

“It’s hard when you don’t fit in your things anymore," says Heidi, who posed for the provocative cover when she was 3 months pregnant. "The last month is unbelievable, how rapidly your stomach goes. It’s huge. The thighs, the butt—everything explodes in the end. But it’s bizarre. Just as it’s a miracle that you can grow a human being in your belly, it’s a miracle that your body goes back to normal again. I don’t think you ever get back to exactly the way you were, but you do get close. And I’m happy with that. Especially when you see your kid for the first time.”

Heidi also reveals why her husband of 4 years, musician Seal, is "the one:"

"Aside from his sexy stature? He’s a gentle giant. We’re very into family values. If you come to our house in L.A., you’ll see that it’s not a big, museum-like house where you can’t touch anything or sit anywhere. It’s a family house, where three children [Leni, Henry, and Johann] are living. We have toys all over the place.”
