Pitching in for a worthwhile cause, Christina Aguilera lent her voice to the fight against hunger by filming a new PSA for Yum! Brands' World Hunger Relief effort on Tuesday (July 26).

Dressed in a blue top and black pants, the "Voice" coach was surrounded by a group of children holding candles as cameras captured footage to be turned into the PSA launching this fall in KFC, Pizza Hut and Taco Bell restaurants worldwide.


With the effort to benefit the UN World Food Programme (WFP), Miss Aguilera tweeted, "Just filmed new PSA for @WldHungerRelief by @yumbrands launching in Sept. Share this and grow the movement! FromHungerToHope.com"

With Christina also serving as an “Ambassador Against Hunger” for WFP, the Grammy winning singer previously appeared in World Hunger Relief restaurant posters, including a never–seen–before photo of her in Haiti, accompanied by the quote, “Together, we have the power to save lives and go from hunger to hope."
