Robin Williams has vowed never to marry again.

The 'Mrs. Doubtfire' actor has been married twice - he split from his wife second wife Marsha Garces earlier this year - but claims he has no intention of tying the knot a third time as he couldn't face another failed relationship.

You know, you see someone with one leg and one arm, and you say, 'Hi, Bill, is this your third marriage?' Let's not get to fourth marriages

Asked if he would ever walk down the aisle again, Robin told Britain's Daily Mail newspaper: "No sir! It's not just for the financial reasons. People would think twice about divorce if they had to give up a body part instead of half their fortune.

"You know, you see someone with one leg and one arm, and you say, 'Hi, Bill, is this your third marriage?' Let's not get to fourth marriages."

Marsha filed for divorce in May after 18 years of marriage, citing irreconcilable differences.

The pair - who have two children, 19-year-old daughter Zelda and 16-year-old son Cody - married in April 1989 after meeting when Marsha worked as a nanny for Robin's son Zachary, from his first marriage to Valerie Velardi.

Although no official reason for his split from Marsha has been given, Robin checked into rehab in 2006 to be treated for an alcohol addiction.
