Singer Christina Aguilera appears in a new public service announcement to raise awareness of Yum! Brands World Hunger Relief efforts. In the video available in JustJared.com, Christina talks about hunger in countries such as Haiti and Guatemela where she joined on relief trips.

"I saw the faces of hungry children in Haiti and in Guatemala on relief trips with the World Food Programme and it was heartbreaking," Christina Aguilera shared.

"As a mother, I know how critical the right foods at the right time are for kids and that's why I'm so passionate about fighting hunger and lending my voice to the world of hunger relief effort."

According to the movement's website From Hunger to Hope, for this year, Christina Aguilera and Muhammad Ali joined forces to help the United Nations' World Food Program (WFP) Haiti relief efforts by appearing in a global Public Service Announcement produced by the Yum! Brands Foundation.

As posted in the website:

"Donations raised through Ali and Aguilera's PSA, highlighting a text message and online campaign, went directly to support WFP's efforts to get food to earthquake survivors in Haiti. Yum! also directed $500,000 from its World Hunger Relief effort to help WFP provide food for earthquake victims, and the Yum! Brands Foundation matched all Yum! employee donations up to a system-wide total of $500,000."
