The actress — who plays 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.

“I’m going to need you to go on a testosterone run,” Samantha tells her.

“I’ll do it first thing tomorrow,” Meghan replied.

However, Samantha is not impressed. “I’ll call the pharmacy and tell them you are on your way,” she said.

Testosterone is taken by both men and women if they have fertility problems.

As well as pregnancy rumours, Samantha’s ex-boyfriend Smith Jerrod — played by Jason Lewis — is to make a return after she dumped him at the end of the last movie.

Sex and the City 2 will hit movie theaters May 2010.

Meanwhile, Sarah Jessica Parker – who plays Carried Bradshaw — has revealed her character’s life comes “crashing down”.

“As ever the girls reflect real life and Carrie’s world seems to be crashing down,” Parker, 44, is quoted as saying.
