Robin Williams married graphic designer Susan Schneider in a weekend ceremony, the actor's rep confirms to ET.
The wedding took place at a resort in the Napa Valley town of St. Helena and rumored guests included Steven Spielberg, George Lucas, and Billy Crystal, according to Us Weekly.
Britain's The Guardian newspaper reports the actor/comedian met Schneider shortly before he underwent heart surgery in mid-2009 and she helped nurse him back to health.
It's the third marriage for Williams, who finalized his divorce with second wife Marsha last year. He has three kids: son Zachary, 28, with first wife Valerie; and two adult children, Zelda and Cody, with ex Marsha.
