In Touch has a detailed report on how the stars diet. Victoria's Secret model Gisele Buendchen keeps herself looking good eating liver burgers while Avril Lavigne, rebounding from an all junk food all the time year is sticking to avocados, tomatoes, tuna, almonds and water. Jennifer Love Hewitt eats her potatoes before her meat in the belief that it allows her body to digest the food better. Mariah Carey takes the cake among these dieters; when she wants a snack, she tricks her taste buds into thinking she's eating by sucking on ice cubes. The Bosh wonders if that had anything to do with her divorce from Tommy. (By Scott Rose)
