London: Oscar winning actor Robin Williams is grateful to his wife Marsha for not turning their divorce into a messy and expensive affair.

Contactmusic.com reports that the couple filed for divorce citing irreconcilable differences.

Williams, who has for the first time spoken about the divorce in public, said: "I'm lucky... with someone like Marsha, and we have amazing kids and it's not a slash and burn. I think a lot of times divorce can be like circumcision with a weed-whacker."
