Kristin Davis Pays Tribute to 'Beloved' 'SATC' Costar Willie Garson: 'We Are Bereft Without Him'

Willie Garson, who played Stanford Blatch on Sex and the City, died Tuesday after suffering from pancreatic cancer

Kristin Davis has penned a loving tribute to her late Sex and the City costar, Willie Garson.

Garson died Tuesday at age 57 after suffering from pancreatic cancer. He was perhaps best known for his role as Stanford Blatch, the best friend of Sarah Jessica Parker's Carrie Bradshaw, in the popular HBO series and its spinoff movies.

Prior to his death, he had already filmed scenes for the show's upcoming revival, And Just Like That…, starring Parker, Davis and Cynthia Nixon.

On Wednesday, Davis, 56, shared a series of photos of Garson on her Instagram page, including one of him with his son Nathen. In the caption, she recalled the origins of her friendship with the actor.

"I first met Willie in 1995 on the spooky nighttime set of the X-files," she began. "He immediately made me laugh. Little did I know that we would have the joy of sharing Sex and the City + And Just Like That together. Willie is beloved by our entire community. He was smarter and funnier than you ever would have imagined. We are bereft without him."

Davis, who plays Charlotte York in the beloved franchise, continued, "But I really want to pay tribute to his fearless commitment to single fatherhood. We spoke about being single parents through adoption often. And nothing gave him more joy and pride than his son Nathen. Nathen's strength and wisdom beyond his years are evident in his beautiful tribute to his dad. The outpouring of love is earned dear Willie."

"I am thankful for all of the time we had and grateful that so much of your bright light is on film forever," she concluded. "Maybe we can do our pod cast [sic] the next time around ? We love you forever xoxo."

Various other members of the SATC family also paid tribute to Garson following the news of his death, with creator Darren Star describing him to PEOPLE as "sweet, soulful and hilariously funny."

"Willie touched all of us with his big heart and generous spirit," Star said. "The man behind Stanford was a loving father, a mensch to his friends and radiated kindness to all. He is gone much too soon."

Nixon, who starred as Miranda Hobbes in the original series and is reprising her role for the reboot, shared her tribute on Twitter.

"So deeply, deeply sad we have lost @WillieGarson. We all loved him and adored working with him. He was endlessly funny on-screen and and in real life. He was a source of light, friendship and show business lore. He was a consummate professional— always."

Mario Cantone, Garson's on-screen husband in SATC, posted a photo of the friends on Instagram Tuesday, sharing his grief in the caption.

"I couldn't have had a more brilliant TV partner. I'm devastated and just overwhelmed with Sadness," Cantone wrote. "Taken away from all of us way soon. You were a gift from the gods sweet Willie. Rest …I love you."
