Heidi Klum Says Four Kids Is Perfect

Heidi Klum seems to juggle motherhood and work with relative ease, but the model mom insists her fourth baby - she and her husband Seal are expecting a girl in the fall - will be her last.

"We're outnumbered,"she tells USA Today. "Four is perfect. Three is a lot. But four? It's a lot of work. We're hands-on, and we feel like this is what we can handle."

Heidi, 36, says the new baby will just add to the happy chaos that already exists in the family's home.

"Actually, they've taken over already," she admits of kids kids Leni, 5, Henry, 3, and Johan, 2. "I'm not someone who is like, 'OK, this is a museum, and you can't sit here and you can't touch this and everything has to be put in its place.' They live there as much as we do. You come into our house, and there is a giant elephant and lion to welcome you. We have those big stuffed animals, and we have toys and things everywhere."

Heidi seems to be ready to welcome the family's newest member, although there is at least one thing left on her baby to-do list: Picking the perfect name!

"Because we know it's going to be our last baby, it's way harder. We've never had this back and forth before. Before it was like, 'This is the name and that's that.' We're going to wait until we see the baby and hopefully the light bulb will come on and then it'll be like, ding-ding-ding!"
