She’s an actress-turned-clothing designer-turned-humanitarian.

And now with new that there will finally be a ‘Sex and the City’ movie, Sarah Jessica Parker’s plate is fuller than ever. (Figuratively speaking, of course.)

In the August issue of Elle magazine, the stick-thin 42-year-old actress offers her take on everything from her personal style to the key to a successful Hollywood marriage.

SJP on family: “James Wilkie is so conscious now of the time we spend together,” she says of her four-and-a-half-year-old. “I try to be home to tuck him in at least four nights a week, and if I’m not, he’s not letting me get away with anything. The other night I was sitting with him on the steps before Matthew and I went out to the theater, and he looked at me and said, ‘Mama, this has got to stop. Go upstairs and take that dress off.’”

SJP on marriage: “Actually, it’s not hard to be a private couple,” Parker says. “I see some people who do it really well, and then I see people who make me skeptical about their deep desire to be so private. It’s like, ‘Are you sure that’s what you really want?’” She and Broderick learned long ago to avoid the dual red-carpet walk. “That’s where they get you. Suddenly it becomes, ‘Oh, when are you guys going to have another baby?’” she says, in a tone firmly implying that, if she were to tell, it wouldn’t be to anyone wielding a tape recorder. “We try not to talk about the relationship. It’s not that we’re not proud; it’s just that’s the kiss of death.”

SJP on the Sex and the City movie: “I am hopeful. I believe this time it’s going to happen,” Parker says, choosing her words. It turns out her optimistic attitude was well-warranted: Just last week, it was revealed that HBO and New Line Cinema would have all four ladies reprising their roles in a big-screen version of the Emmy Award-winning series. After three years of eager whispers, Parker and her co-stars can finally clear the air. “I really wanted it to happen, and it was a bitter pill to swallow that it didn’t,” Parker says, setting the record straight. “But you have to respect people’s decisions. And one of us didn’t want to do it at the time, meaning Kim [Catrall], for reasons that I didn’t ask. It’s not for me to talk anybody into anything, ever-creatively, financially, or whatever.”

SJP on her personal style: “Carrie loved the hits and she loved the misses, and I loved being able to wear all that without being indicted for it in my own life,” the actress says. “But I would never consider wearing some of the outfits she wore. Like, ever. The last thing I need is to call attention to myself when I walk down the street.”

SJP on her clothing line, Bitten: “Parker picked Steve & Barry’s—a chain of big-box stores that says (with no apparent sense of irony) its mission is to change the world because she wanted to offer women the little-black-dress equivalent of a $14.98 sneaker designed by New York Knicks point guard Stephon Marbury—which is, to date, Steve & Barry’s biggest success. “There are millions of kids in America who spend $210, $220 on a pair of freaking sneakers that, by the way, are going to go out of fashion in no time,” Parker says. “Stephon Marbury creates this shoe, and it’s the shoe that he is really playing in on the court. And it’s $15. And kids can have a really cool pair of shoes, and their parents can live with themselves. The idea that quality shouldn’t be a privilege and that luxury shouldn’t be just exclusive? I love that.”
