George Clooney is calling on all of his famous pals to help raise funds during his Hope For Haiti Now telethon.

Christina Aguilera, Justin Timberlake and Taylor Swift have signed on to appear during Friday's fundraiser, to air on networks including NBC, CBS, ABC, CNN, and MTV. More than one hundred other film and TV personalities will lend their time and talents to raise funds to benefit the earthquake- rocked island nation.

Clooney will anchor the telethon from Los Angeles, Wyclef Jean in New York City and CNN's Anderson Cooper will report live from Haiti.

Proceeds from the two-hour Hope for Haiti Now event will benefit The Clinton Bush Haiti Fund, United Nations World Food Programme, Oxfam America, Partners in Health, the Red Cross, UNICEF and Yele Haiti.

House's Olivia Wilde had just returned from Haiti when the earthquake struck.

"I am gutted by this catastrophe," Wilde, who works with Artists for Peace and Justice, says in a statement to UsMagazine.com. "Right now, their team on the ground needs money desperately to help dig people out of the collapsed hospitals and schools, to buy emergency medicine, to supply badly needed water and food, to help fly in doctors for the wounded children, and so much more," she continues. "Any amount helps."

Find out how you can help at the Red Cross (text "Haiti" to 90999 to donate $10 to the organization).
