If the rumours about their feud are true, then Kim Cattrall must be a very brave woman. Because Sarah Jessica Parker looks as though she would pack a mean punch.

Miss Parker paraded a pair of bulging biceps as she launched her range of perfume in Paris.

The 43-year-old actress obviously squeezed in a few gym sessions during her punishing tour to promote the Sex and the City film.

Fitness expert Vicky Warr said: "She looks like she has done a lot of high-resistance training focused on her biceps and triceps.

"It is common for women of this age group to do this type of exercise as it is good for anti-ageing and speeds the metabolism."

Miss Parker and Miss Cattrall, her Sex and the City co-star, are said to be barely speaking. At the film's premiere in London last week they did not even sit through the screening together, with Miss Cattrall leaving early.

Israeli advertising executives have censored their billboard campaign for the movie, removing the word 'sex' from adverts in two cities for fear of causing offence. The word will be replaced by three dots.
