Actors Julia Roberts and Brad Pitt were also in attendance during the two-hour Hope For Haiti telethon, which was broadcast on all major US TV channels, websites including YouTube and on MTV in the UK. It was also broadcast on Haiti’s Radio One.
“At the core of every religion is the belief that we care for one another, we take care of each other especially in times of need,” said Clooney. “The Haitian people need our help, they need to know they’re not alone, they need to know that we still care.”
An estimated 1.5 million people have been left homeless by the 7.0-magnitude quake. At present the death toll is thought to be 150,000.
During the show, Beyonce sang ‘Halo’, accompanied on the piano by Chris Martin.
She changed the lyrics, and sang “Haiti we can see your halo, we pray you won’t fade away“.
More than 100 Hollywood actors and musicians took part, with some of them, including director Steven Spielberg and Stevie Wonder, manning the phones to take donations from the public.
Clint Eastwood, Meryl Streep, Nicole Kidman, Robert De Niro, Matt Damon, Denzel Washington, Daniel Craig and Jack Nicholson were among the other names rounded up by Clooney to take part.
Madonna, who performed ‘Like A Prayer’ during the show, donated $250,000 (£155,000), Brad Pitt and Angelina Jolie gave $1m (£620,000) while supermodel Gisele Bündchen gave $1.5m (£0.93m). Clooney himself donated another $1m.
As well as donations from viewers, more money will be raised through the sale of songs performed on the show, via iTunes.
