Kim Cattrall stormed out of Sex and the City reunion party, it has been reported.

The actress was "scowling" as she left the bash at New York's Butter restaurant to celebrate the start of filming Sex and the City: The Movie.

One diner told the New York Daily News newspaper: "Kim left earlier than the others and was wearing a scowl.She was just shooting a dirty look at the paparazzi."

Kim's co-stars Sarah Jessica and Kristen Davis remained unfazed by her hasty departure and continued to enjoy the evening.

The source added: "Thirty minutes later the other two left, with big smiles on their faces.Kristen climbed into a town car and Sarah looked like she was walking home."

Kim's swift exit has sparked rumours she has reignited her feud with Sarah Jessica.

Reported tension between the pair was said to be the reason behind the big screen adaptation being delayed.

At the time, a source close to Kim revealed: "Kim Cattrall does not want to sign on to do the film. She feels she has been treated horribly by Sarah Jessica Parker for six years - so why would she want to revisit that for one moment?"

Sex and the City: The Movie is set to be released in the US on May 30 next year.
