In news that will devastate women of a certain age, it turns out that two of the glamorous foursome at the heart of Sex and the City can't stand each other in real life.
Kim Cattrall, who played the show's best character, Samantha, has revealed her anger at Sarah Jessica Parker, who played Carrie, the worst character ever written.
After Parker left a sympathetic message on Cattrall's Instagram post about her brother's death, Cattrall called her former co-star a "hypocrite" and "cruel" in a later post.
While fans of the show may be dismayed, it's far from the only instance of co-stars who secretly hated each other.
Ryan Gosling vs Rachel McAdams
The stars of every basic white girl's favourite movie did not get on while filming The Notebook.
According to the film's director Nick Cassavetes, Gosling asked him to replace McAdams with another actor who could read her character's lines off-camera.
Cassavetes told VH-1 that he held an impromptu therapy session for the two actors, shutting them in a room alone together so they could "work out their differences" by screaming at each other. It apparently worked and filming was "smoother sailing" from then on.
Gosling and McAdams can't have hated each other entirely, because they dated for two years after filming wrapped.
Bette Davis vs Joan Crawford
A feud so iconic it needed Susan Sarandon and Jessica Lange to do it justice on the small screen in last year's Feud: Bette and Joan.
The two legends of cinema starred in 1962's Whatever Happened to Baby Jane?
After she was snubbed by the Academy, Crawford famously sabotaged Davis' chances at winning her third Best Actress Oscar.
She bad-mouthed Davis to members of the Academy, and told other nominees she would accept their statue on their behalf if they won to save them the expense of going to the ceremony.
Not only did Davis not win Best Actress, it was Crawford who accepted the award onstage on behalf of Anne Bancroft in The Miracle Worker.
The two failed to make up before Crawford's death in 1977, about which Davis devastatingly remarked:
"You should never say bad things about the dead, only good. Joan Crawford is dead. Good."
R2-D2 vs C-3PO
Doesn't this just break your heart? R2-D2 and C-3PO may have bickered a lot onscreen, but the two robots clearly cared for each other.
The same can't be said of the actors who played them. In a 2009 interview with Metro, Kenny Baker (R2-D2) said Anthony Daniels (C-3PO) "doesn't get on with anyone".
He said he'd approached Daniels multiple times about the two of them going on tour, but Daniels "looked down his nose at me like I was a piece of shit".
"He said, 'I don't do many of these conventions - go away little man.' He really degraded me and made me feel small."
Apparently the two actors barely talked while filming the nine Star Wars films they have both appeared in so far.
Daniels told The Mirror something similar in 2011.
"I never saw him. I mean, R2-D2 doesn't even speak. He might as well be a bucket."
Harsh words from the golden robot man.
Bill Murray vs Lucy Liu
Neither of these two stars seem like they'd be difficult to get along with, but rumour says otherwise.
While filming the excellent Charlie's Angels reboot in 2000, Murray allegedly told Liu she couldn't act. She then began punching him and the two had to be physically pulled apart.
Murray later remembered the incident as just a "brief spat", but it must have been serious because he was replaced by Bernie Mac in the role of Bosley in the sequel.
That's got to hurt.
Gillian Anderson vs David Duchovny
Scully and Mulder hating each other in real life is such a sad thought. Take comfort in the fact that their off-screen animosity seems to have stemmed simply from getting sick of each other while filming The X-Files.
At the 1997 Golden Globes, Duchovny thanked Anderson in his Best Actor in a TV Series acceptance speech, but Anderson failed to do the same when she won Best Actress.
This stoked rumours that the two co-stars secretly despised each other, which neither actor ever explicitly denied.
"Did David and I hate each other?" Anderson wrote on her official website in 2007.
"At times yes, like any brother and sister, husband and wife, co-worker and co-worker forced to spend that much time together under such strenuous circumstances."
Duchovny told Metro UK much the same thing.
"Familiarity breeds contempt. It's nothing to do with the other person," he said.
"We used to argue about nothing. We couldn't stand the sight of each other."
Dakota Johnson vs Jamie Dornan
Sometimes silence says it all.
Fifty Shades of Grey stars Johnson and Dornan have never demonstrated even a hint of affection for the person they've pretended to have rough sex with in three blockbuster films.
The two play passionate lovers whose romance borders on the obsessive, but they seem to barely tolerate each other in real life.
In every promotional photo for the films they gaze blankly into the camera while coldly holding hands, and in talk show appearances, they keep their distance.
But perhaps ignoring each other is part of the whole dom-sub thing and they're both just very committed to their roles.
Who are we to judge?
