Robin Williams' wife, Marsha Garces Williams, has filed for divorce after 19 years of marriage. She filed her petition March 21 in San Francisco, saying that she and Robin had "irreconcilable differences." The pair met and married in 1989, shortly after Williams divorced his previous wife. They have an 18-year-old daughter, Zelda, and a 16-year-old son, Cody, together. People reports that Garces Williams is asking for joint custody of Cody, as well as monies for attorney fees and spousal support. Robin and Marsha, who met when she was a nanny for Williams' son from his previous marriage, have worked together over the years. They eventually formed Blue Wolf Productions, which released films like

Mrs. Doubtfire and Patch Adams, as well as a nonprofit that supports the arts and environmental, health and education causes. - Anna Dimond
