Christina Aguilera is taking on a new role - as the international spokesperson for the World Hunger Relief organisation.
The singer, who is a mother of one, has joined the campaign in a bid to highlight the plight of millions of children who face death by starvation every year.
Aguilera took to the street of Hollywood on Wednesday (16Jul09) to film a public service broadcast to send her message across America.
And she hopes her fame can push people into helping the cause.
She says, "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."
