A Personal Message from George...
The people of Haiti need our help. On Thursday, February 4th, I am throwing a benefit concert called "Help Haiti" at the Nokia Theatre L.A. LIVE here in Los Angeles. The best musicians, comedians and athletes will be there for the cause, including my friends Andy Garcia, Slash and Samuel Jackson.
One-hundred percent of the proceeds will go to directly to Haiti to help the victims and their families. Keep checking this page for more information on how to purchase tickets for "Help Haiti."
Additional participants announced on the site: Kobe Bryant, Cedric the Entertainer, Don Cheadle, Margaret Cho, Cypress Hill, Larry David, Vanessa Hudgens, Ozzy Osbourne, and Ray Romano.
Tickets are available for purchase here.
