Sarah Jessica Parker says she and hubby Matthew Broderick are keeping the sex of their first baby a surprise.

"The suspense is important to us," says the blond star of Sex and the City

"Getting pregnant was a surprise in the first place. We weren't really planning it, although we were thrilled when it did happen, and we thought we'd keep the sex a surprise, too." 

Parker is due to give birth at the end of October and says she's made no attempt to find out whether the child a girl or a boy. 

Once the stork arrives, Parker plans to take time off work until February, when she's set to begin filming the HBO hit's next season. 

Producers have had to conceal her tummy on the show after deciding her real-life pregnancy would not be written into the storyline. 

And the actress told yesterday's edition of London's Mail there's absolutely no chance of her character, Carrie, ever having a baby. 

"For one thing, Cynthia Nixon's character, Miranda, just had a baby, and simply in logistical terms, one baby on the show is hard enough to cope with," she said. 

"Besides, I wouldn't want Carrie to have a child. It wouldn't be right for her."
