Robin Williams may be going through a tough time – but at least he has a slew of famous friends to lean on for support.

Williams’s wife of 19 years, Marsha Garces Williams, filed for divorce last week, citing irreconcilable differences.

Since the split, the comedian’s License to Wed costar John Krasinski said they’ve talked “a bunch of times.”

“He’s been so supportive of me since the movie and still keeps in touch,” the Office star told PEOPLE Monday night at the L.A. premiere of his new film, Leatherheads. “That just shows you what a classy guy he is, to keep tabs on people that he cares about.”

So does Williams still have his signature sense of humor during these difficult times? “Absolutely!” said Krasinski. “Absolutely – if not better.”

I’d like to read a tell-all from this lady because if Robin Williams isn’t still on drugs, I just don’t know what his deal is! Actor Robin Williams and his wife of 19-years, Marsha Garces Williams, are getting divorced. Marsha filed for divorce on March 21, 2008 stating “irreconcilable differences” as the reason. She just chose that because “my husband is an annoying crack head” wasn’t an option! Just kidding.. but seriously, Robin Williams is pretty wacky, isn’t he?

The couple got married in 1989 and have two children together; an 18-year old daughter and a 16-year old son.

I don’t know the pre-nup situation but Marsha is a producer (she produced Mrs. Doubtfire and Patch Adams) so she must have some of her own money. Let’s hope this doesn’t turn ugly like the divorce of Bassinger-Baldwin!
