Heidi Klum has no qualms about gaining weight during her pregnancy.  “I’m not worried,” said Klum. “I know my body will go back again!”

The Supermodel who is pregnant with her fourth child says that she welcomes any changes to her body.

“Certain things you get used to,” Klum told Usmagazine. “You get used to all the changes of your body. It’s not like I’m going, ‘Oh my God!’ I’m used to that part of it.”

As for her children — Leni, 5, Henry, 3, and Johan, 2 –, they have a lot of fun rubbing their mommy’s belly.

“They get it,” said Klum. “They always rub my tummy.

Leni, who says that her mom’s belly “[feels] like a Buddha”, likes to embarrass her mom in public.

“If I had a dress on, Leni would literally go all the way down under my dress to rub my tummy. And I go, ‘My underwear is showing, thank you very much!'”
