Australian actress and singer Delta Goodrem is the latest star to throw her support behind a global campaign to bring an end to chronic hunger.
The United Nations Food and Agriculture Organisation's One Billion Hungry Project was launched in May 2010 with the aim of pressuring governments worldwide to end chronic global hunger in our lifetime.
"When I began to understand the vast extent of hunger in the world today there was no way I could not get involved," Goodrem said in a statement.
"The fact that a billion people on this planet are not getting enough to eat is simply unacceptable. And here's a chance to do something about it."
Goodrem will appear in the campaign's new TV ad that juxtaposes the singer with a homeless woman of the same age scrounging for food in a dump.
The ad will hit the internet and television screens in Australia later this week.
Scott Grove, the project's manager, said the goal to eliminate hunger and extreme poverty "is totally feasible if all countries, rich and poor, make it their priority".
"Delta Goodrem's powerful appeal is an amazing asset for us as we reach out to young audiences," he added.
A number of celebrities have already backed the project, including Hollywood actress Susan Sarandon, Canadian singer Céline Dion, US track and field legend Carl Lewis, Chilean writer Isabel Allende and Brazilian President Luiz Inacio Lula da Silva.
The campaign had already attracted more than three billion signatures by November, from farmers in Guatemala, Boy Scouts in Egypt, baseball players in Italy, agricultural workers in Nepal, and hundreds of thousands of individuals online.
