Kevin James and Leah Remini are the king and queen of throwbacks this week as “The King of Queens” co-stars commemorate the 25th anniversary of the beloved sitcom.

The pair — who played spouses Doug and Carrie Heffernan, respectively — each took to Instagram Thursday to pay homage to the series, which ran on CBS for nine seasons from 1998 to 2007.

“25 years ago today, we aired. I am so incredibly blessed to have taken this ride with the insanely talented @leahremini and Jerry Stiller,” 58-year-old James, who scored an Emmy nod for his role, captioned a promotional shot of the trio. “I love you both so much… and thank you to the GREATEST FANS in the world!”

Stiller co-starred as Carrie’s live-in father — and the thorn in Doug’s side — Arthur. The “Seinfeld” alum died in New York in May 2020 at the age of 92.

Remini, 53, shared a clip from “The King of Queens” as well as a promo photo of herself, James and Stiller.

“By the time I signed on as Carrie Heffernan, I had been to hundreds of auditions, was cast in many pilots and some short-lived series, and was finally offered ‘The King Of Queens,’ Remini wrote. “As soon as production started on season one, I knew I was home.”

She praised her “amazing” co-stars, all of whom she said “made me laugh every day,” and noted that the “gifted guest and recurring cast made the show what it is.”

Remini gave a special shout out to the fans who “fall asleep every night” to the series or say it helped them “through a rough day and tough time in your lives, that you laughed for the first time in your day watching us … or that you and your family bond over watching.”

“It means the world to me, and I’m so grateful for this experience that lives on and on,” said Remini.
