Sarah Jessica Parker and Kim Cattrall's alleged ongoing feud is threatening the future of the second 'Sex and the City' movie.

The actresses - who didn't get on when they filmed the six series of the TV show and the first movie adaptation in 2008 - are said to dislike each other so much they refuse to talk to one another, leaving the rest of the cast and crew feeling uncomfortable on set.

Kim Cattrall's character tries to get pregnant in the new "Sex and the City" movie. The actress - who plays sex-obsessed PR guru Samantha Jones in the hit film and TV series - was spotted carrying her script for the highly-anticipated film which revealed her alter-ego is using testosterone hormones, which are sometimes taken to help women conceive.

In one scene between Samantha and her assistant Meghan, the blonde maneater knocks over a container of hormones and orders Meghan to go and get some more.

Kim Cattrall has reportedly split from her long-term partner.

The 52-year-old actress' relationship with chef Alan Wyse - who is 20 years her junior - is said to have run its course after nearly five years together.
