For Heidi Klum, there can never be too many cooks in the kitchen.

That's because preparing meals at her home is a family affair, one that involves all four of her children.

"[My kids] cook everything with me. They barbecue with me, they chop with me. The little one washes," the "Project Runway" host told Us Weekly during an event Thursday for the charity organization God's Love We Deliver. "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."

The "America's Got Talent" personality dished on other lessons she's taught the kids - Leni, 10, Henry, 8, Johan, 7, and Lou, 4, whose father is Klum's ex-husband, Seal.

"My son Henry carved his name into the dining room table," the 41-year-old model told 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.' I'm like, 'Think of all the pieces of furniture in the house as little Ferraris, OK?' He got it."

Klum is also teaching her children about the importance of giving back, like donating toys they don't play with anymore or volunteering, as she does regularly for God's Love We Deliver, a non-profit group that provides meals for people who are too sick to cook for themselves.

"I've been helping for the last 10 years, because I think what they do is important," Klum told Us.

Another fan of the organization was the late Joan Rivers.

"Joan brought love, compassion and humor to every delivery she made and every event she supported," the organization wrote in a statement on its website. "Joan's impact on God's Love will be felt always by our clients, volunteers, staff and community. Rest in peace, Joan. You will forever be in our hearts."
