Mariah Carey Named Ambassador For Hunger Charity

Mariah Carey is ready to give back as the global ambassador of a hunger relief charity. She'll be the front woman for the Yum! Foundation to raise money for the United Nations World Food Program.

In her role, Mimi will appear in posters in more than 36,000 Pizza Huts, Taco Bells, and KFCs all over the country. But of course there's a twist!

Mariah is asking people to donate to the cause by downloading her song Love Story at FromHungerToHope.com. 25 cents from each download will go to the foundation. Preview the song here...
