Stylist Rachel Zoe pretty much sums up the only reasonable reaction to the latest bikini pictures of a—yowza!—46-year-old Demi Moore
. "Her body," says Zoe, who's pals with the actress, "is ridiculous!" To get it that way Moore does Pilates, has worked out to the P90X DVDs (which have cardio and yoga programs) and sticks to a mostly organic diet. Still, "she eats what she wants," says Zoe. Pasta and popcorn make the cut. Chocolate? Not so much. "She just doesn't like it," says pal Heather Parry, a producer. "That's the only annoying thing about her!"
