What follows are five well-documented cases where co-stars projected warmth on screen while something far cooler was happening behind the scenes. These aren’t rumors pulled from anonymous tabloid sources. Each one has been confirmed, at least in part, by the people involved themselves.
1. Sarah Jessica Parker and Kim Cattrall
No modern TV feud has been dissected quite as thoroughly as the one between the two “Sex and the City” stars. A 2008 report claimed Cattrall attempted a salary raise, and a 2018 article reiterated tense contract negotiations before each season. By the time the show ended, Cattrall confirmed on a talk show in 2004 that money contributed to the show ending after six seasons, saying she felt it was time for everyone to share in the financial windfall.
Things got worse once a third movie was floated. The feud between the two actresses seemingly began after plans to film a third “Sex and the City” movie fell apart, with Cattrall making contractual demands that Warner Bros. wouldn’t meet, according to Parker. Parker has since said Cattrall was never asked to reprise her role in “And Just Like That” because of what she had already said publicly, and that she wouldn’t be okay with Cattrall returning given the public history of feelings Cattrall had shared.
2. Shannen Doherty and Alyssa Milano
The “Charmed” rift stayed buried for over two decades before Doherty’s own podcast cracked it open. Doherty and co-star Holly Marie Combs revealed that Doherty was fired from “Charmed” due to an alleged ultimatum Milano gave producers, threatening to sue for a hostile work environment if the network didn’t choose between them. According to Combs, it was Milano who strong-armed the producers into firing Doherty after three seasons.
Milano has pushed back on that framing but not denied that things were rough. Milano told Entertainment Weekly it was hard putting two very different people together, describing herself as laid-back while calling Doherty headstrong, and said it was unfortunate that Doherty left and badmouthed everyone involved. The two never fully reconciled before Doherty’s death in July 2024, and Doherty, who passed away in July at age 53 after being diagnosed with cancer in 2015, had starred alongside Milano on the show that aired between 1998 and 2006.
3. Suzanne Somers and her “Three’s Company” castmates
This one started as a straightforward pay dispute and turned into a decades-long freeze-out. By 1980, Somers had graced the cover of numerous magazines and knew her worth to the show, so when contract negotiations came up, she set a threshold equal to her male co-star, not expecting to walk out jobless. The show’s response, according to Somers, was essentially “Who do you think you are,” insisting John Ritter was the star.
The fallout was not limited to network executives. Somers left the series after five seasons because of the pay dispute, and it resulted in a rift with the “Three’s Company” cast that took many years to repair. It wasn’t until three decades later that Somers and co-star Joyce DeWitt sat down together again, and the two hadn’t spoken since Somers was fired over the salary dispute, finally reuniting on Somers’ web series, where Somers admitted she probably upset her castmates by treating the show as a business venture.
4. Katherine Heigl and the “Grey’s Anatomy” cast and crew
Heigl’s tension with her show wasn’t a secret feud so much as a very public one. Her tensions were pretty public, mostly because she was really public about them, and after winning an Emmy in 2007 she withdrew her name from consideration the following year, saying she felt she wasn’t given material to warrant a nomination, a comment widely seen as a dig at the writers. She later told David Letterman that the actors’ long workdays on set were “cruel and mean,” and shortly after requested to be let out of her contract early, leaving the show mid-season in 2010.
Money played a role behind the scenes too. In 2007 she reportedly became upset when salary bumps went to Ellen Pompeo, Patrick Dempsey, Isaiah Washington, and Sandra Oh, according to a book on the show’s inside history. Years later, in a joint interview with Ellen Pompeo, Heigl reflected on the period by admitting she’d been naive and had “some things to say” at the time, not expecting such a strong reaction.
5. Kelly Ripa and Michael Strahan
Not every feud on this list involves scripted drama; some of the coldest TV rifts happen live, on morning television. The relationship between Ripa and Strahan turned tense after his abrupt 2016 departure from “Live With Kelly and Michael,” with Ripa reportedly finding out about his move to “Good Morning America” minutes before it was publicly announced. Ripa was memorably blindsided despite her name appearing first in the show’s title, and she took off a few days to process the news before returning to address it on air, speaking about the need for communication, consideration, and respect in the workplace.
Strahan has since acknowledged the exit was clumsy but rejected the idea that he orchestrated it. He suggested he was not treated as Ripa’s equal during his four years on the show, saying he didn’t know he was supposed to be a sidekick when he thought he was going there to be a partner. Nearly a decade later, as Strahan’s “Good Morning America” moved into the same building as Ripa’s current show, the network was reportedly bracing for a potential run-in between the two former co-hosts.
None of these five pairings ever fully erased what happened behind the scenes, though a couple of them eventually found their way to something like peace. What ties them together isn’t malice so much as ordinary workplace friction, over money, credit, or respect, playing out under lights that made it look effortless. The cameras caught the performance. They never caught the whole story.
