German supermodel Heidi Klum always keeps her weekends free for her children. The 39-year-old raises kids Leni, nine, Henry, seven, Johan, six and Lou, three, with former husband Seal. Despite her busy schedule, she tries to spend quality time with them whenever possible. “I keep weekends open and wrap my workday at a reasonable hour so I’m home for dinner and bedtime stories,” contactmusic.com quoted Klum as saying.
