She tweeted a fan that she has moved on

(CNN) That "Sex and the City" sequel is really not going to happen.

Kim Cattrall, who played Samantha Jones on the long-running HBO hit, is far from friendly with the rest of her former castmates.

"We've never been friends," Cattrall said in an interview with Piers Morgan's "Life Stories" scheduled to air on Monday night.

The series, which went off the air in 2004, revolved around Sarah Jessica Parker's character, Carrie Bradshaw, and her core group of girlfriends as they navigated life and love in New York. The subsequent movies were released in 2008 and 2010.

Cattrall has been taking heat from fans who blame her for "Sex and the City 3" being called off.
