Nathen Garson, the only child of Sex and the City alum Willie Garson, paid tribute to his late father on what would have been the star's 58th birthday.
"Happy birthday, papa," Nathen, 20, wrote on Instagram on Feb. 20 alongside a throwback photo of himself with his father. "Miss you tons and love you."
The actor, who played fan-favorite character Stanford Blatch on HBO's Sex and the City, died at age 57 of pancreatic cancer in September, which was just weeks after he finished filming scenes for the sequel series And Just Like That...
Despite playing an openly gay man on Sex and the City, he identified as straight and was set up on a date with Parker years before they filmed together. He told Out Magazine in 2000 that they "settled into being best friends, something I think really reads on the show."
At the time, Nathen posted a tribute to his dad on Instagram, which read,
"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."
Nathen would go on to join his dad's co-stars, including Sarah Jessica Parker, Cynthia Nixon, and Kristin Davis, at the premiere of And Just Like That... last December.
In the fourth episode, the series addressed his character's departure, paying tribute to the actor himself in the credits, which read, "In memory of our beloved Willie Garson."
