Is Heidi Klum expecting number four? The answer is yes, according to In Touch Weekly. A source close to Klum and her husband, Seal, revealed that the Project Runway host’s wardrobe helped spill her secret. Apparently, someone posted sketches of Klum’s redesigned gowns online, and the extra room for a baby bump was clearly visible. The couple have three children: Leni, nearly five; Henry, 3 and Johan, 2.
