TV presenter, stylist and model Becca Dudley has been announced as ambassador of MTV's Staying Alive Foundation, set up to fund innovative projects and produce TV and online content to help fight HIV.

Dudley, a keen humanitarian who spent two months in Kenya, commented 'I strongly believe that the most effective way to change the awful stigma of HIV is through education and conversation. I honestly feel that if I can spread the message through The MTV Staying Alive Foundation and make an impact on at least one person, I have already started to make a difference'.
