Comedian Robin Williams is heading for a divorce – his wife Marsha has filed papers in a California court requesting a legal separation.

Producer Marsha Garces Williams, who had been married to the actor for 19 years, filed the petition in San Francisco last Friday (21Mar08) citing irreconcilable differences for the split.

The pair first met while Williams was still married to his first wife Valerie and Marsha was working as the couple’s nanny. They married in 1989, just months after the breakdown of his first union.

Robin and Marsha often worked together – she produced his films Mrs. Doubtfire and Patch Adams – and they founded Blue Wolf Productions and the organization Doctors Without Borders.

They have two children together: daughter Zelda, eighteen, and seventeen-year-old son Cody.
