Rapper/actor Mos Def and actress Susan Sarandon have joined forces to encourage obese youngsters to slim down. The two stars have been named Honorary Co-Chairs to the Fourth Annual Children's Sports & Fitness Expo, which is due to take place in New York in September.

Vincent Ferguson, the brains behind the annual event, hopes the added star status will make children more aware of the health dangers of being overweight. He tells AllHipHop.com, "With their support we hope to bring more attention to the fact that one in three children born since 2000 will get diabetes according to the New England Journal of Medicine. Children will lose three to five years off of their lives because of obesity. This is a call to action."
