Kristin Davis (search) gets no downtime once she returns home from her whirlwind of event-hopping at the Olympic Games.

The "Sex and the City" (search) star is developing her own series for HBO, the same cable channel that made her character, prim Charlotte York, a household name, along with Carrie, Miranda and Samantha.

"I've been working on it for a little while," Davis told The Associated Press Thursday night while attending a Sports Illustrated party at a trendy beachfront lounge.

She couldn't say much about what the show will be like, but she divulged, "It's really fun and odd being on the development side. I'm working with all the executives for the show, and to see the way that ideas come together and people come together is fascinating."

Davis has been in Athens with the committee that's trying to bring the summer Olympic Games (search) to New York in 2012. The 39-year-old also is Maybelline New York's new celebrity spokeswoman and will appear in the cosmetics brand's TV and print ads that will debut at the end of the year.

For her role on "Sex and the City," which ended its six-year run in February, Davis also is up for an Emmy for supporting actress in a comedy series, alongside co-stars Kim Cattrall (news) and Cynthia Nixon. Sarah Jessica Parker is nominated for lead actress in a comedy.
