Willie Garson — famous for his role in the “Sex and the City” series and movies — has died … according to his close friends.

“Bosch” star Titus Welliver broke the news of Willie’s passing with a post that said, “There are no words. I love you dear brother. We are fewer,” and he attached a photo of Willie.

Willie’s fellow actor and friend Rob Morrow also posted a tribute.

Sources connected to the ‘SATC’ star tell us he’d been battling cancer, though we’ve not confirmed it as his cause of death.

Willie was a fan fave from the hit HBO series … playing Sarah Jessica Parker’s male BFF, Stanford Blatch — a gay socialite who Carrie Bradshaw often called “Stanny.”

He didn’t appear in every episode, but for the 27 he did pop up for over the course of 6 years … his scenes were always memorable.

Willie was also in both ‘SATC’ movies … and he’s at least slated to appear with SJP and co. in “And Just Like That…” — the new HBO Max series. We know he shot scenes in NYC this summer with Sarah Jessica and Mario Cantone.

WG’s roles went well beyond ‘SATC’ though — he’s been in tons of shows and movies throughout his career … including stuff like “White Collar,” “Hawaii Five-0,” “Quantum Leap,” “Girl Meets World,” “Mr. Belvedere,” “Just Shoot Me!” “Big Mouth,” “Supergirl,” and many, many more.

He’s got a total of 170 acting credits to his name, dating back to the ’80s.

Willie was 57. He leaves behind his son, Nathen.

RIP
