The newest spokesperson for Jenny Craig, Mariah Carey decided to team up with the American Heart Association to bring awareness for heart disease. Carey lost 30 pounds after the birth of her twins and decided that getting healthy wasn’t just about your image, but also about taking care of yourself. Heart disease is still the #1 killer of adults in the United States. It’s important that we take care of ourselves. Love it when celebs use the spotlight to bring awareness to something important.
