Robin Williams and wife to divorce

SAN FRANCISCO (AP) -- After nearly 19 years of marriage, Robin Williams and his wife are getting divorced. Marsha Garces Williams filed a petition for dissolution of marriage on March 21 in San Francisco Superior Court, citing irreconcilable differences.

The two met when Garces Williams worked as a nanny for Williams' son Zachary, whom he had with his previous wife, Valerie Valardi.

Robin and Garces Williams also have two children together, Zelda and Cody.

Williams' agent Mara Buxbaum confirmed that the couple is splitting, but had no further comment. An attorney for his estranged wife would not comment on the case.
