There's no such thing as too many cooks in the kitchen at Heidi Klum's house! The America's Got Talent judge, 41, likes to involve all four of her kids when she prepares meals at home — even the littlest one, 4-year-old Lou, has a job to do, she told Us Weekly at a Sept. 4 event for the organization God's Love We Deliver, which provides meals for people who are too sick to cook for themselves.

"[My kids] cook everything with me. They barbecue with me, they chop with me. The little one washes," the Project Runway host told Us. "Everyone has their part to do, because I think it's important they see how food is made, how a dish is made. A lot of younger people nowadays don't know how to cook. No one taught them. So I think it's important to teach that to them." 

She imparts other crucial lessons, too — like the fact that forks are for eating, not carving letters into furniture. "My son Henry carved his name into the dining room table," the German-born model shared with Us. "I said, 'What's your favorite sports car?' He said, 'A Ferrari.' So I said, 'Well, imagine you had a Ferrari and I took a knife and wrote Heidi all over the hood,'" she recalled. "I'm like, 'Think of all the pieces of furniture in the house as little Ferraris, okay?' He got it."

Klum is also teaching her kids the importance of giving back. Whenever there are toys they don't want to play with anymore, or duplicates of a game they already have, she gives the product away. She also donates her time to God's Love We Deliver, a nonprofit that was also near and dear to the late Joan Rivers.

"I've been helping for the last 10 years, because I think what they do is important," Klum told Us of the organization. "They help so many families and elderly people who are too weak to get up to shop for food, to cook food. A lot of these people are on medication or bedridden."

Thanks to God's Love We Deliver, though, they have access to "fresh, home-cooked food" every day, she explained. "So all these volunteers come every day, five days a week, sometimes seven days a week, and then everything is freshly cooked and gets delivered during the day."
