It's no secret to anyone that Christina Aguilera has an incredibly powerful voice. She's now using it for good by helping to spread awareness about hunger.

Aguilera has been an inspirational spokeswoman and an Ambassador to the United Nation's World Food Programme (WFP). The legendary singer has been openly speaking about the challenges of feeding the world’s growing population of 7 billion and counting, and has also helped raise awareness about the work WFP has been involved in to fight this social issue affecting so many.

Christina is continuing her work during the Thanksgiving season by showing her fans how fighting hunger is not only a great way to give back, but also an important one. On November 21, she will be auctioning off two tickets on eBay to her NBC show “The Voice”. Winners will also get the opportunity to meet Christina backstage in Los Angeles.

Now don't worry if you don't have Christina's killer pop-star voice. You can still be like the pop diva by doing something about hunger this holiday season.
