Kristin Davis
Kristin Davis turned 40 on Feb. 23, and she's feeling just fine about it. "Age is a state of mind," she says. Proving it, she's the face of Maybelline New York. "It's great that actresses that aren't twentysomethings are being offered contracts by cosmetic companies. Women of all ages are beautiful."

As far as acting, Davis will play moms in her next two films, The Adventures of Shark Boy & Lava Girl in 3-D (out June 10) and the remake of Disney's The Shaggy Dog (costarring Tim Allen), and in an ABC comedy pilot Soccer Moms.

Cynthia Nixon
Since Sex, Cynthia Nixon has been juggling motherhood and work as an advocate for New York City's public schools. The actress recently filmed the comedy Little Manhattan (costarring The West Wing's Bradley Whitford), and she'll return to TV as Eleanor Roosevelt in the biopic Warm Springs. On the homefront, the 38-year-old actress – who split in 2003 from longtime partner Danny Mozes (the father of her kids, Samantha, 8, and Charles, 2) – has been dating New York City education activist Christine Marinoni for the past year.

The Men of Sex:
Chris Noth

David Eigenberg
David Eigenberg (Miranda's husband Steve on Sex), 40, is starring in an independent comedy, Love, Ludlow, which premiered at the Sundance Film Festival. He's also done recent guest spots on Without a Trace, Judging Amy and Everwood.
