She's off to a good start, thanks to extreme moisturizing measures dictated by you-know-who. "Every time I see her, she's offering me creams," says Jones, whose favorite is Crème de la Mer. "I have eye cream, face cream—I even have eyelash moisturizer!" It's paying off, says Lipton, who cites Jones's skin as her best asset—but doesn't want to leave out "her eyes, nose, mouth, teeth, cheekbones, forehead and eyebrows!" All that and brains too: She earned a B.A. from Harvard in 1997 and "was always a bookworm," says her dad, who would catch her at age 5 "under the covers with a flashlight and five books." To keep her 5'3" frame in grade-A shape, Jones, who dates New York City deejay Mark Ronson, 26, works out with a personal trainer near her L.A. home and watches her dairy, starch and sugar intake. One favorite indulgence, she says, is "taking 10-minute catnaps. I can fall asleep anywhere."
