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 chains of restaurant, reported Daily Star.
"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," she said.
The new PSA will air from this month.
