Heidi wore a pink bikini top, daisy duke shorts, and a Gucci fanny pack. The year-old reality and mother-of-one uses the meal delivery plan to help maintain her ideal weight and stay healthy, a stark contrast from the way she used to live her lifestyle. Audrina, who has a three-year-old daughter with ex-husband Corey Bohan, modeled a stunning two-piece by Bikini Planet Blue. She also donned a green and yellow neon silk dress by Alexis and acute, front tie Los Angeles t-shirt by Aqua. As part of the photoshoot, Audrina also put her styling skills to use to help a real-life South Beach Diet success story — Nicole Ballantine, who recently lost 30 pounds to find her own style and update her wardrobe. The two met for the first time last month in Venice Beach, California where Audrina presented her with an afternoon styling session.
