Kim Cattrall and Sarah Jessica Parker have allegedly been embroiled in a long-running feud dating back to the Sex and the City TV series.
But now things seem to have taken another turn, with a very telling sign emerging that the feud is still ongoing.
Kim, 66, stars in a brand new Netflix series titled Glamorous, which dropped onto the streaming platform today (June 22).
And fans have spotted something a little "catty", which could be a swipe at her former friend.
Today also marks the day that the second series of Sex and the City spin-off And Just Like That... dropped onto Max, which has left fans in a frenzy.
Fans quickly rushed to Twitter after spotting the "shady" move, with many obsessed with the "cattiness" of the situation.
"Netflix dropping the Kim Cattrall show the same day as AJLT is such a move... I love cattiness," penned one fan.
While another added: "Kim Cattrall's new Netflix show coming out the same day as the new season of "..And Just Like That is sending me."
"Has anybody clocked Netflix is releasing Kim Cattrall’s new show the same day they are beginning season two of And Just Like That? Lol," noted a third.
A fourth then simply asked if it was a "coincidence", while a fifth said: "Kim Cattrall announcing her new Netflix show, Glamorous, is coming out the same day as And Just Like That season two (June 22) is absolutely iconic behavior."
"The tea is piping," added another, while someone else offered: "Same day as the new season of and just like that drops… shady boots!"
In Glamorous, the Samantha Jones actress plays the role of beauty mogul Madolyn Addison, a character very reminiscent of Miranda Priestly in The Devil Wears Prada.
A former high school student, who makes YouTube videos and creates content online, then lands the job of a lifetime working for Madolyn.
The young student-turned-makeup-hopeful is played by Miss Benny and in the series is a gender-nonconforming queer makeup artist named Marco Mejia.
Kim Cattrall and SJP have allegedly been at loggerheads for several years, although denying this on several occasions.
When the Sex and the City television series came to an end, there had already been reports that Kim, Sarah, Kristin and Cynthia didn't get along in real life as much as their on-screen characters.
And in 2017, a New York Post article claimed that Sarah and Cynthia became pals on-set rather quickly, with them soon including Kristin, but leaving Kim out and feeling a bit isolated.
Despite previously denying a feud, when Liverpool-born Kim appeared on Piers Morgan's Life Stories she said: "We've never been friends - we've been colleagues," and added that SJP could have been kinder and "nicer".
