"[It was] kinda on the spur of the moment," he said. "We just decided Leap Day would be the best time to do it."
Van Dyke met Silver, 40, six years ago at the SAG Awards and hired her as his personal makeup artist shortly thereafter. "The last couple of years we kind of fell in love," he said. "She keeps up with me."
This is the second marriage for the longtime actor, who is best known for his role in Mary Poppins and the TV series The Dick Van Dyke Show and Diagnosis Murder. He has four children with his first wife, Margerie Willett.
