In addition to hosting the Hope For Haiti telethon tomorrow evening, George Clooney is donating $1 million to the relief efforts to help the nation - and he's not the only one in the million dollar club! Sandra Bullock, Gisele Bundchen and Brad Pitt and Angelina Jolie have all made seven figure donations, and hopefully even more celebs will be added to this list.

It's just been announced that Madonna and Beyonce will be joining the star studded roster, which already includes celebs like Leonardo DiCaprio, Rob Pattinson, Jennifer Aniston, Jake Gyllenhaal, Brad Pitt, Ellen DeGeneres, Sandra Bullock, Zac Efron, Bradley Cooper, Renee Zellweger, Chris Pine, Courteney Cox, David Arquette, Colin Farrell, Anderson Cooper, Wyclef Jean, Gabby Sidibe and Emily Blunt. Rihanna, Justin Timberlake, Taylor Swift, Alicia Keys, Christina Aguilera, Shakira, Jay-Z, Bono and Bruce Springsteen are all set to perform in Los Angeles, New York and London.

Check out the first promo for the telethon, which will air on over a dozen networks tomorrow at 8pm:
