Mariah Carey is making a run for the border...for a good cause.
The Grammy winner has signed on as the latest Hunger Ambassador for the Yum! Foundation's World Hunger Relief, an annual effort that aims to raise money for the United Nations World Food Program and bring an end to starvation around the world.
Her duties include becoming the actual poster child for the cause, appearing on print ads that will be featured in more than 100 countries and 36,000 franchises.
"The change from hunger to hope starts with you," Carey's poster reads.
