How has life changed for Klum since becoming a mother twice over? "Two kids' car seats, more diapers and, as any new parents will tell you, less sleep," the supermodel, 32, says of life with Henry, 5 months, and Leni, 2. One thing that hasn't changed is her workload. Eight weeks after the birth of her son, the Project Runway host was on the catwalk in lingerie. "If you like what you do, you can juggle everything," she says.
