LOS ANGELES: Robin Williams' wife has filed for divorce from the Oscar- winning actor after a 19-year marriage, People.com reported on Wednesday citing the star's spokeswoman.

Marsha Garces Williams filed for divorce petition at a court in San Francisco on March 21 citing irreconcilable differences, reports said.

Williams' representative, Mara Buxbaum, confirmed the divorce to People but was not immediately available for comment.

Garces, 51, and Williams, 56, married in 1989, shortly after the actor's divorce from his previous wife. The couple have two children, an 18-year-old daughter and a 16-year-old son.

Garces has worked as a producer on several of Williams films including "Jakob the Liar", "Patch Adams," and "Mrs. Doubtfire."

Williams won a best supporting actor Oscar for his role in the 1997 film "Good Will Hunting" and has been nominated for an Academy Award for three other movies: "Good Morning Vietnam," "The Fisher King," and "Dead Poets Society." - AFP/fa
