Willie Garson, the character actor known for his roles on “Sex and the City” and “White Collar,” died at the age of 57, according to Variety.

A family member confirmed the death to the outlet but did not disclose a cause.

Garson became a familiar face to the millions who watched HBO’s “Sex and the City,” in which he played talent agent Stanford Blatch, best friend of Sarah Jessica Parker’s Carrie Bradshaw. He reprised his role in both films, and had been filming for the network’s upcoming revival series, “And Just Like That,” Variety reported.

In addition to his work on the series, Garson co-starred as con man Mozzie on USA Network’s “White Collar,” from 2009 to 2014. The versatile actor was also a mainstay in many films, such as “Little Manhattan,” “There’s Something About Mary,” and “Groundhog Day.”

In 2009, Garson adopted his son, Nathen, and continued to be a fierce advocate for adoption.

Nathen memorialized Garson on Instagram on Tuesday.

“I love you so much papa. Rest In Peace and I’m so glad you got to share all your adventures with me and were able to accomplish so much. I’m so proud of you. I will always love you, but I think it’s time for you to go on an adventure of your own,” he wrote.
