Kristin Davis gave an intimate look at her close bond with her late pal Willie Garson, who died at 57 following a secret battle with pancreatic cancer.
As the actress grieved her Sex and the City costar, she shared a heartfelt tribute that described him as someone who could 'immediately' make her laugh.
'I first met Willie in 1995 on the spooky nighttime set of the X-files,' the 56-year-old Emmy nominee recalled. 'Little did I know that we would have the joy of sharing Sex and the City + And Just Like That together.'

She continued: 'Willie is beloved by our entire community. He was smarter and funnier than you ever would have imagined. We are bereft without him.'
The performer, who became a mom to her two children Gemma and Wilson through adoption, went on to pay homage to his 'fearless commitment to single fatherhood.'
'We spoke about being single parents through adoption often,' Davis told her more than one million Instagram followers. '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,' she added.
The Deadly Illusions star concluded: 'I am thankful for all of the time we had and grateful that so much of your bright light is on film forever. Maybe we can do our podcast the next time around? We love you forever xoxo.'
Garson adopted his 20-year-old son Nathan, when he was just seven and a half.

Cynthia, who played Miranda Hobbes on the show, gushed over Willie, who starred as 'gay talent agent' Stanford Blatch, and spoke of how 'endlessly funny he was on-screen and in real life,' while Kim, who played the fiery Samantha Jones, called his passing: 'A terribly sad loss for the SATC family'.
Willie's son Nathen confirmed the news on Instagram on Tuesday, while another family member spoke to Variety. A TMZ source said the actor had been 'battling cancer.'

His passing comes amid filming for the revival series And Just Like That..., leaving the future of storylines uncertain. He was last seen visiting the set on 3 August.
Willie's last sighting saw him on-set clutching a script, a coffee and a takeaway food container, while his final social media message came two days later, when he penned: 'BE KIND TO EACH OTHER......ALWAYS. LOVE TO ALL. APRROACH KINDNESS', on September 5.
While his most famous role was playing Stanford, who was gay, Willie was heterosexual and after being in a long-term relationship with a woman who did not want children, he opted to adopt Nathen alone in 2009.
