Madonna, Sandra Bullock, Lady GaGa, Tiger Woods, Joe Jonas and others are opening their hearts and wallets to help the victims of the devastating earthquake that rocked Haiti last week.

Sandra Bullock, who enjoyed her most successful box office year ever, donated a whopping $1 million to Doctors Without Borders, while Madonna gave $250,000 to Partners In Health.

The Tiger Woods foundation is rumored to have donated as much as $3 million dollars to the cause, while Lady GaGa announced she will be donating proceeds from her upcoming Radio City Music Hall show in New York to the Haitian victims.

But Joe Jonas said he wanted to do more than donate. The Disney star is apparently planning a trip to the ravaged nation to help out in person.

George Clooney has organized a telethon with countless celebrities participating, that will air on Friday, Jan. 22, at 8 p.m. on ABC, CBS, NBC, Fox, the CW, CNN, BET, HBO, MTV, VH1 and CMT, wihout commercial interruption.
