A Los Angeles commissioner has approved Klum's request to formally change her name to Heidi Samuel, People reports. It is unclear whether Klum will use her new name professionally.
Klum and Seal have been married for four years. The couple have two sons, Henry, 4, and Johan, 3, as well as daughter Lou Sulola, born last month. Klum also has another daughter, five-year-old Leni, with Italian businessman Flavio Briatore.
