Mom-to-be Heidi Klum, her husband Seal, and their two children Leni, 5, and Henry, 3, were photographed at LAX Airport on August 05, 2009.

Heidi, who is known for her svelte figure, recently spoke about how she has kept in shape  all these years

“I’ve never really had any special girdle machines or anything like that,” she said. “For me, it’s, you know, really healthy foods, exercising, playing with the children, going to the park. Normal things.”

“I’ve never done diets,” she added. “But I also do not sit on the couch with my feet up and eat one potato chip bag after the next and one burger after the other. I think you have to kind of do a little bit of everything.”

The mom of three also believes in getting back in shape immediately after pregnancy.

“I never really put a lot of pressure on myself, but for me personally, I feel like it is always better to get into shape immediately. I feel like if I drag it out too long, I’m not going to do it,” she said. “So for me it works to kind of get back into shape, afterwards, I feel great. I can put my normal clothes back on and it makes me happy, and it’s worked so far.”
