"Well, there's an opening," she tells the CBS late-night host.
The actress, who played Carrie Bradshaw in the hit HBO series and movies, jokingly offered the CBS late-night comedian the job during a "Late Show" appearance Wednesday.
Colbert figured SJP, who currently stars on HBO comedy "Divorce", was tired of answering questions about a possible "Sex and the City 3" movie, so he decided to change it up and ask what part he would play.
"Well, there's an opening," SPJ joked. "According to just very recent documentation about why we're not making it is because the part usually played by Kim Cattrall has been vacated. So that's what I mean. Perhaps you'd want to play Samantha?"
"I'm kind of a little slutty, a little fun," Colbert replied.
The exchange comes after a whole lot of drama occurred in late September when SJP confirmed that the possibility of a third movie was dead. Reports subsequently emerged claiming Cattrall's "outrageous demands" and lack of interest were holding up the project.
"I'm disappointed. We had this beautiful, funny, heartbreaking, joyful, very relatable script and story," SJP said in an interview. "It's not just disappointing that we don't get to tell the story and have that experience, but more so for that audience that has been so vocal in wanting another movie."
Cattrall later openly admitted on Twitter that she didn't have any desire to make another "Sex and the City" movie, but denied her "demands" had anything to do with production shutting down.
"Now at this very moment it's quite extraordinary to get any kind of negative press about something that I've been saying for almost a year of 'no' that I'm demanding or a diva," Cattrall said. "And this is really where I take to task the people from 'Sex and the City,' and specifically Sarah Jessica Parker, in that I think she could have been nicer."
