Supermodel, "Project Runway" host and mother of four Heidi Klum passes on her eco-consciousness to her kids. "I think we live in a world where you buy more than you need. I try not to buy too many things so that I don't have to throw out that many things. I try to teach my children that they have to eat what's on their plate and why. You have to start in your family."

Starting Feb. 1, Klum will host a new weekly show for Lifetime called "Seriously Funny Kids," which is kind of a hybrid of Bill Cosby's "Kids Say the Darndest Things" (or Art Linkletter's earlier "House Party") and "Candid Camera," with Klum staging hidden camera bits and eliciting innocent out-of-the-mouths-of-babes hilarity from kid interviewees.

"They're so unpredictable. You never know what you get, which is fun and challenging for me. You just have to go wit the flow, so I can't really prepare for it," says Klum, who often finds it hard to keep from cracking up in bits like the one in which she pretended to be a talking goldfish. "But I have to keep a straight face, because I don't want to let them in on it."

Her own brood (with husband Seal) won't be part of the show, but she assures, "they are hilarious." Klum will return with another installment of "Project Runway" this summer.
