Christina Aguilera films emotional PSA for hunger relief campaign

CHRISTINA AGUILERA has put her vocal talents to good use and recorded a public service announcement to raise funds for a hunger relief campaign.

The Beautiful hitmaker is a global spokesperson for the United Nations World Hunger Relief, the charity behind the Yum! Brands' global relief drive, which is backed by its restaurant chains KFC, Pizza Hut and Taco Bell.

The new PSA will air in October (12) and depicts a mother's emotional battle as she struggles to provide food for her starving child.

In the video, Aguilera urges viewers to give hungry kids a voice as her soulful song The Voice Within plays in the background.

She says, "The concept of my new PSA for Yum! Brands' World Hunger Relief effort really moves me, not just because I'm a mother, but because it speaks to anyone who has ever struggled to feed their children.

"It is a devastating issue but one that we can help solve and that's why I'm so passionate about using my voice by raising awareness."

The singer has served as global spokesperson for Yum! Brands' World Hunger Relief effort since 2009.
