Actress also gives Andy Cohen a chance to audition for the role of Samantha during "WWHL" interview.
"Just heartbroken," SJP told Andy Cohen on "Watch What Happens Live" Wednesday. "I mean, that whole week, you and I spoke about it endlessly, because I was just, I don't know, I found it very upsetting because that's not the way I recall our experience."
After Cattrall confirmed a third "SATC" movie being dead in water because she was never interested in reprising her role as Samantha, she appeared on "Piers Morgan's Life Stories" and spilled on her relationship with the rest of the cast.
"We’ve never been friends," Cattrall said. "We‘ve been colleagues and in some ways, it’s a very healthy place to be because then you have a clear line between your professional life and relationship and your personal."
"They all have children and I am ten years older and since specifically the series ended I have been spending most of my time outside of New York so I don't see them," Cattrall continued. "The common ground that we had was the series and the series is over."
SJP sees things differently, though.
"It's sad, but I always think that what ties us together was this singular experience," she told Cohen. "It was a professional experience, but it became personal because it was years and years of our lives, so I hope that that eclipses anything that's been recently spoken. That many years spent doing something so special that people had a connection with it is such a privilege."
The 52-year-old "Divorce" star is still optimistic the franchise could carry on without Cattrall.
"I think once everybody has thoroughly experienced the grieving process, then [producer] Michael Patrick [King] can go back and sort of ponder what he might want to do and how he might want to proceed," she said. "That's the most clear answer I've given yet."
SJP previously jokingly offered the role of Samantha to late-night host Stephen Colbert and daytime talk show host Ellen DeGeneres, but gave Cohen the opportunity to audition, complete with a blonde wig.
"I'm willing to go on the record and say you're more suited certainly than Stephen Colbert and I don't know that Ellen's actually interested. In fact, she might have passed," SJP said. "So, the part by default is yours!"
