Celebrities from the world of music and film have gathered in New York to raise money for the victims of the Haiti earthquakke.
Rapper Wyclef Jean joined acts such as Sting, Alicia Keys and Bruce Springsteen for the “Hope for Haiti Now” fundraiser.
The two-hour charity telethon was organised by actor George Clooney and broadcast on all major US television networks.
A host of stars took donations by telephone, while viewers also gave via SMS or the Internet.
Clooney, who is giving one million dollars of his own money to the campaign, urged Americans to be generous in their donations.
“It’s a tragedy that reaches across all borders, all boundaries, and demands our attention, our help, and our compassion as fellow human beings,” Clooney told viewers.
Madonna sang a version of her classic single “Like a Prayer”, while British band Coldplay also performed.
Lead singer Chris Martin explained why they took part.
“When something that terrible and tragic happens, you have to play to your strengths to do anything you can to help,” Martin said.
Performing from London, hip-hop star Jay-Z teamed up with Rihanna and Irish rock stars U2 to debut their charity single, Stranded (Haiti Mon Amour).
The record is available to download from various Internet retaliers from Saturday.
