The world's most adorable family took Manhattan onThursday. "Project Runway" host Heidi Klum and her hubby, musicianSeal, grabbed all four of their gorgeous little tykes -- Henry, Johan, Leni,and baby Lou -- and hit up Toys 'R' Us in Times Square. Proud papa Seal evencarried a camera like a real tourist! Later, the happy couple and theirpint-size crew grabbed dinner at swanky sushi spot Nobu. If 20-month-old Lou isalready eating spicy tuna rolls, we're impressed!
