George Clooney says the "Hope for Haiti" benefit for victims of the earthquake in Haiti will include performances from Bono, Sting, Justin Timberlake, Christina Aguilera and Alicia Keys.

Speaking to The Associated Press at the Golden Globes ceremony at the Beverly Hilton Hotel, Clooney said that more than 40 celebrities are expected to attend the Jan. 22 event. The actor said the aim of the benefit is "to show the people of Haiti that the whole world is paying attention."

The benefit, which Clooney and Haitian-born singer Wyclef Jean will host, will be broadcast on more than a dozen broadcast and cable networks. It will be held in New York, with CNN's Anderson Cooper chiming in from Haiti.

The show will benefit the Red Cross, UNICEF, Oxfam America, Partners in Health and Jean's Yele Haiti Foundation.

Clooney said that songs from participating artists will also be available on iTunes, with proceeds going to the relief effort.
