The streaming platform made the announcement on Twitter on April 2, Friday, ala a report from resident gossip columnist Lady Whistledown.
"Dearest Readers," the message began. "While all eyes turn to Lord Anthony Bridgerton's quest to find a Viscountess, we bid adieu to Rege-Jean Page, who so triumphantly played the Duke of Hastings. We'll miss Simon's presence onscreen, but he will always be a part of the Bridgerton family. Daphne will remain a devoted wife and sister, helping her brother navigate the upcoming social season and what it has to offer—more intrigue and romance than my readers may be able to hear. Yours truly, Lady Whistledown."
"Your Grace, it has been a pleasure," Netflix's caption read.
Bridgerton officially became Netflix's most-watched series ever as of February 1.
The original book, "The Duke and I" by Julia Quinn—which the series is based on—focuses on a different Bridgerton sibling in each of its volumes.
Bridgerton creator Shonda Rhimes also had a note to fans on Instagram.
"Remember: the Duke is never gone. He’s just waiting to be binge-watched all over again. #ShondalandMenOnNetflixAreForever" she wrote.
Celebs like Anne Curtis couldn't help but express her devastation, reacting to Shonda's post. "Why??????" the actress replied, with several crying face emojis.
Rege-Jean paid tribute to his character on Instagram, sharing a photo of the duke riding a horse.
"The ride of a lifetime," he wrote. "It’s been an absolute pleasure and a privilege to be your Duke. Joining this family - not just on screen, but offscreen, too. Our incredibly creative and generous cast, crew, outstanding fans — it’s all been beyond anything I could have imagined. The love is real and will just keep growing."
We'll terribly miss our Duke of Hastings! Sob.
