All is not well in cosmo-land according to reports coming out of the set of the new Sex and the City 2 movie.

We all knew that Sarah Jessica Parker and Kim Cattrall had their differences, but being well accomplished actresses they manage to fool us all both on the small, and the big screen. But they cant fool themselves and eventually their hostile feelings for one another float to the surface just like an olive in one of Samantha’s dirty Martinis!

Along with her dislike of Cattrall, Parker, who plays the main character of columnist, Carrie Bradshaw, now has a larger brood to contend with back at the old homestead. Since becoming a mother to surrogate twin girls, Marion and Tabitha, earlier this year, the 44 year old wife of Broadway star, Matthew Broderick, is said to be finding  it increasingly difficult to juggle family life and her work schedule.

“The crew have taken to calling her ‘Carrie Sadshaw’. When she doesn’t have to be ‘on’ in her scenes, she looks so sad,” the source said. “Kim has been taking every chance to snipe. You could cut the tension with a knife. Their fighting has also made Cynthia Nixon and Kristin Davis miserable, too.”

The, not so happy foursome, are putting pressure on the production of the eagerly awaited Sex and the City 2 movie, due for release in May 2010.
