The gloves are off in the long-simmering feud between Sex and the City stars Kim Cattrall and Sarah Jessica Parker.
Facing widespread media reports that it was her outrageous demands that scuppered a third Sex and the City movie - and with SJP herself fuming that she was "disappointed" tolet down audiences - Cattrall went on the defensive in a new interview with Piers Morgan.
"I don't know what her problem is, I never have," she said, labelling her co-star "toxic" and saying she "wishes she could have been nicer" to her.
So the cat's finally out of the bag - but Cattrall and SJP are far from alone. Hollywood is littered with famous feuds, co-stars who had to play nice for the camera but couldn't stand the sight of each other.
Speaking at a Comic-Con panel in 2014, Prinze slammed his former 24 co-star. "Kiefer was the most unprofessional dude in the world ... I think everyone that worked with him would say that", he said.
The former teen star even said his stint on 24 made him want "to quit the business."
Jim Carrey vs. Tommy Lee Jones
How's this for a one-sided feud: Carrey was very excited to work with Lee Jones on the 1995 blockbuster Batman Forever. The feeling was in no way mutual.
"I was the star and that was the problem," Carrey reveals in a new interview. "He's a phenomenal actor, though. I still love him."
He said he bumped into the veteran actor in a restaurant just before filming started.
I went over and I said, 'Hey Tommy, how are you doing?' and the blood just drained from his face."
"And he got up shaking - he must have been in mid-kill me fantasy or something like that. And he went to hug me and he said, 'I hate you. I really don't like you.' And I said, 'What's the problem?' and pulled up a chair, which probably wasn't smart. And he said, 'I cannot sanction your buffoonery,'" Carrey recalled.
Charlize Theron vs. Tom Hardy
Actress Zoe Kravitz, who starred in Mad Max: Fury Road alongside Hardy and Theron, didn't hold back when asked in an interview this year if she'd witnessed the rumoured feud between the pair.

"Huh, yeah," she said.
"They didn't get along but we were also in the desert for so long. "I actually don't know if it was one issue. I just think they weren't vibing," she said.
Theron herself admitted she and Hardy struggled to get along during filming.
"Maybe the movie is what it is because we struggled so much with each other, and those characters had to struggle so much with each other. If we were chum-chum, maybe the movie would have been 10 times worse."
Pierce Brosnan vs. Teri Hatcher

Pierce Brosnan has openly admitted that he struggled to form a bond (pun intended) with his female co-star in the 1997 Bond film Tomorrow Never Dies.
"I got very upset with her," Brosnan told the Daily Mirror. "She was always keeping me waiting for hours. I must admit I let slip a few words which weren't very nice."
Bill Murray vs. Lucy Liu

Rumour has it that Bill Murray stopped a scene during the filming of Charlie's Angels purely to tell Lucy Liu that she couldn't act. Not surprisingly, Liu did not take it well. In fact, she reportedly threw a punch at the Groundhog Day star.
When asked about the onset spat, Murray told the New York Times, "Look, I will dismiss you completely if you are unprofessional and working with me. "When our relationship is professional, and you're not getting that done, forget it."
In the years since, Murray appears to have moved on, saying, "I feel very warmly for her (Liu) now".
Ryan Gosling vs. Rachel McAdams
The Notebook director Nick Cassavetes revealed that Gosling tried to get his leading lady fired from the hit film because he felt the pair had no chemistry.
"Maybe I'm not supposed to tell this story, but they were really not getting along one day on set. Really not. And Ryan came to me, and there's 150 people standing in this big scene, and he says, "Nick come here," Cassavetes said.
"He's doing a scene with Rachel and he says, "Would you take her out of here and bring in another actor to read off camera with me?" I said, "What?" He says, "I can't. I can't do it with her. I'm just not getting anything from this."
Cassavetes said he held an impromptu therapy session in his trailer between the pair.
"They started screaming and yelling at each other. I walked out. At that point I was smoking cigarettes. I smoked a cigarette and everybody came out like, "All right let's do this." And it got better after that, you know?" he said.
"They had it out ... I think Ryan respected her for standing up for her character and Rachel was happy to get that out in the open. The rest of the film wasn't smooth sailing, but it was smoother sailing."
Bea Arthur vs. Betty White
On beloved 80s sitcom Golden Girls Dorothy and Rose were the best of friends, but in real life Bea Arthur couldn't stand Betty White.
"She (Arthur) was not that fond of me," Betty White said in 2011. "She found me a pain in the neck sometimes. It was my positive attitude - and that made Bea mad sometimes. If I was happy, she'd be furious!"
According to Rue McClanahan (who played Blanche), the feud lasted long after the show wrapped up. Apparently in 2002, McClanahan's husband spoke to Bea Arthur and thanked her for inviting him to her Broadway show. "I love Rue." Arthur reportedly said, before adding, "Betty [White] is a cu**."

Not a co-star feud, but just too juicy not to include. Tomlin starred in director David O. Russell's surreal cult classic I Heart Huckabees in 2004 - then, three years later, two videos leaked to YouTube showing the veteran actress and her director engaged in stand-up screaming matches on set.
