Hollywood's Revenge Diets

Healing heartache with Haagen-Dazs? Not Reese Witherspoon. When her seven-year marriage to actor Ryan Phillippe failed, the 5-foot-3 actress didn't turn to comfort food. Instead, she channeled her breakup pain into a new exercise program and healthier eating habits. The result: She lost 10 pounds and shrunk from a size 6 to a 2. "Reese used working out to help with post-split anxiety," says a pal. And she's not the only one. After Drew Barrymore's January split from her beau of five years, Fabrizio Moretti, the 5-foot-4 Music and Lyrics star began to get leaner. "Drew always looks good. Now that she's single, she's trying to keep it up," says a friend of the actress, 32, who has shed an estimated 20 pounds. How did they slim down? What other stars fine-tuned their bods after breakups? For Hollywood's favorite diet tips, recipes and exercise plans that really work, pick up the new issue of Us Weekly, on newsstands this week.
