"Richard will always be a cherished member of the HBO and Curb Your Enthusiasm families. Our heartfelt condolences go out to his family, friends and all the fans who could count on Richard to brighten their days with laughter," a statement posted on HBO's X account read.

Celebrities also poured out tributes for the former stand-up comic. His "Curb Your Enthusiasm" co-star Larry David revealed that he sobbed after learning of Lewis's passing.

"Richard and I were born three days apart in the same hospital and for most of my life he's been like a brother to me," the "Seinfeld" co-creator told Fox News.

"He had that rare combination of being the funniest person and also the sweetest. But today he made me sob, and for that I'll never forgive him."

"Ellen DeGeneres Show" producer Andy Lassner also paid a touching tribute to the "7th Heaven" actor.

In his post on Instagram, Lassner said Lewis "saved me" after helping him get back to rehab for his previous drug addiction.

"I guess what I want to say is he was one of the many angels in my life who saved me. And my regret today is not staying in touch," he wrote.
