HOMETOWN: Los Alamitos, Calif.
LATEST GIG: Sex and the City
•Why you know him: This former model (who has appeared in ads for Versace, Tommy Hilfiger and Guess?) has gained exposure as Kim Cattrall's latest love interest, actor Smith Jerrod. Exposure is the operative word, since Lewis has appeared nude in several episodes, including one on a Times Square billboard, covered only by a strategically placed Absolut vodka bottle.
•In the beginning: Raised by Gregory, 64, a superior court judge, and Nancy, 51, a nurse (who divorced when Jason was 21), "I was kind of an odd character as a kid," Lewis says. "I hung out with the football jocks, the skaters and the hardcore punks. It was great."
•His take on taking it all off: "I did have apprehensions," says Lewis, "but I like laughing at myself about it. Laughing makes it easier. My sister Nicole refuses to watch the show while I'm on it. She doesn't really want to see my naked butt!"
•How fans have reacted: "The other day a girl asked if she could give me to her friend as a birthday present," says Lewis (who's unattached). "I was like, 'That's sweet, but I don't think so.'"
