Willie Garson's son, Nathen Garson, celebrated the premiere of "And Just Like That" with the cast of the show, a moment that had to have been bittersweet.
The premiere of the highly-anticipated sequel to "Sex and the City" came less than three months after Willie, who played the beloved Stanford Blatch, passed away.

"What a wonderful trip and what an amazing time I got to have. Thanks @justlikethatmax for a wonderful time and for inviting me to enjoy the season premiere of And Just Like That! Go check it out on HBOmax," Nathen caption a series of images with Chris Noth, Cynthia Nixon, Kristin Davis and Sarah Jessica Parker.
Willie adopted Nathen back in 2009 when he was 7 years old.
On Sept. 21, the 19-year-old announced on Instagram that his father had died from pancreatic cancer. Prior to that, Willie had not publicly disclosed his illness.
Although Willie was a large part of "Sex and the City," his death is not addressed in the sequel.
"Nobody's dead," showrunner Michael Patrick King told the New York Times last week. "Because it wasn't charming. And I knew that the audience would know."
In announcing Willie's death on Instagram, he wrote, "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. You'll always be with me. Love you more than you will ever know and I'm glad you can be at peace now. You always were the toughest and funniest and smartest person I've known. I'm glad you shared you're [sic] love with me. I'll never forget it or lose it."
