Petite powerhouse Christina Aguilera has accepted the role of international spokesperson for the World Hunger Relief organization.

The “Fighter” hitmaker took to the street of Hollywood on Wednesday to shoot a public service announcment she hopes will raise awareness about the cause.

“It’s unacceptable a child dies every six seconds somewhere around the world from hunger. By lending my voice for World Hunger Relief, I hope to raise awareness about the issue and move people from hunger to hope,” Aguilera said in a statement this week.
