Nobody likes to see their staff or coworkers constantly bickering, but when it comes to Cattrall and her Sex and the City co-star Sarah Jessica Parker, they've reportedly fought for more than a decade.

The trouble may have begun after Parker became an executive producer during the show's second season. That's when Cattrall reportedly tried to negotiate a higher salary, which allegedly caused tension between her and SJP.

Cattrall said the dirty stories about money squabbles were nothing but "juicy gossip," telling the Daily Mail, "The truth of us being friends and getting along and happily doing our jobs together is nowhere near as newsworthy. I think Sarah is fantastic. She is a born leader and she guides the crew and the cast in such a strong but gentle way. She and I are sick of this. It's exhausting talking about it, and a real bore. Next?"

But this beef proved to be more than a "real bore" because in 2017, Cattrall told Piers Morgan that she thought Parker "could have been nicer" as a co-star. "I don't know what her issue is," she said (via The Cut). "I never have."

And in case all of that wasn't jaw-dropping enough, we can't forget about Cattrall's 2018 Instagram attack – the one in which she lashed out against Parker voicing sympathy over the death of Cattrall's brother. "I don't need your love or support at this tragic time," she said. "...You are not my family. You are not my friend."

Ouch.
