If Molly Sims could give any celebrity a makeover, she says it’d be Britney Spears. “I would take away the boots, the tank tops,” Sims, 37, says in the September issue of Health magazine. “She’s so pretty-she just needs help with dressing. She gets too many trends going at once.” But the actress and cover model admits that she’s had her own share of flawed fashion moments. “I had braces for two-and-a-half years, and I promise you, I wouldn’t have been the same girl if I didn’t. I would not have smiled.” In fact, Sims tells the magazine that she’s “not not a proponent of cosmetic surgery.” And as someone whose life has centered around the importance of looks, she says, “I think I’ve done every crazy diet there was in the beginning, but it’s weird: I’m thinner now than I was when I was modeling.” To hear more from Molly, pick up the September issue of Health, on newsstands Friday. —Dahvi Shira
