Sarah Jessica Parker on Sexiness and Success

Feb. 24, 2006 — -- Sarah Jessica Parker has been a successful actress since childhood, when she starred in "Annie" on Broadway, but it wasn't until her iconic role as a single woman desperately seeking Mr. Right in the hugely successful HBO series "Sex and the City" that she became a certified celebrity.

In her soon-to-be-released film, "Failure to Launch," Parker is again playing a woman who falls for a reluctant bachelor, played by Matthew McConaughey.

In real life, Parker lives a much more stable romantic life. She has been married to actor Matthew Broderick for nine years, and they have a 3-year-old son, James.

The show was so popular it even spawned a "Sex and the City" bus tour that takes fans by Carrie's apartment and some of the New York hot spots featured in the show.

"I'll tell you something, we wrapped the show two years ago, Feb. 4. ... The last line that I ever uttered, working as an employee on "Sex and the City" was 'And you can drive up and down this street as much as you want, because I don't live here anymore,'" Parker tells Barbara Walters in an exclusive interview with "20/20."

Walters spoke with Parker at one of her favorite West Village haunts, and asked what it was like to work with McConaughey, whom People magazine named the sexiest man alive.

McConaughey is sexy, Parker admits, but she tells Walters she prefers her own Matthew's sexiness.

"Sexy is a very subjective thing. And I appreciate and can completely understand why he has been appointed this, you know, or given this title. However, my husband, Matthew Broderick, has qualities that are, to me, really incredibly sexy. ... You really can't compete with him. You know, just his sense of humor or ... his dry-as-a-bone wit or his peculiar perspective on the world or his cynicism, frankly," she says.

Unlike her characters, Parker is happily and comfortably settled into marriage and motherhood. "I'm not saying it's a perfect marriage. And I'm not saying that we don't disagree about things or that I don't annoy him constantly, as I'm certain I do. And that he doesn't, you know? And that there aren't endless issues that enter into things, like, the toilet seat, or picking up his laundry. But for the most part, we seem to have, I don't know, we seemed to have figured it out," she tells Walters.
