Robin Williams: a married man again. (Gus Ruelas/Reuters)

The Academy Award-winning actor, 60, married girlfriend Susan Schneider, a graphic designer, Sunday in Napa Valley, Calif., Us Weekly magazine reports.

This is the third marriage for Williams, who finalized his divorce from second wife Marsha Garces Williams — to whom he was married for 19 years — in 2010. Williams and Schneider, who also confirmed the weekend wedding plans to the San Francisco Chronicle, reportedly began dating in 2009, around the time Williams had heart surgery.

Us reports that all three of Williams’s children — Zelda, 22, and Cody, 19, from his second marriage and Zachary, 28, from his first marriage to Valerie Velardi — attended the ceremony at the Meadowood resort. Celebrity friends Steven Spielberg, George Lucas and Billy Crystal were reportedly present as well.
