Actor and comedian Robin Williams tied the knot with Susan Schneider, a graphic designer, on Saturday in California.

Williams' third wedding took place at Napa Valley's Meadowood Resort, in the presence of their friends and family.

The couple has been seeing each other for a few years and declared themselves in a serious relationship in 2009, after Williams recovered from a heart surgery.

Williams' first marriage was to Valerie Velardi in 1978, with whom he has one child, Zachary Pym. In 1989, he married Marsha Garces, his son's nanny, who was already several months pregnant with his child. They have two children, Zelda Rae and Cody Alan.

The wedding festivities rage on but my tired feet are done. Think it's time to lay in the tub, eat M&M's and write, Williams' daughter and actress Zelda tweeted.
