NEW YORK, (Reuters) – A benefit for Haiti that will  feature dozens of stars and a collaboration by U2 singer Bono  and rapper Jay-Z will be the most widely distributed telethon  to reach viewers across the globe, MTV said yesterday.

George Clooney, the actor who organized the event, will  host the two-hour “Hope for Haiti Now” show starting at 8 p.m.  EST tomorrow (0100 GMT on Saturday) to raise money for the  earthquake-ravaged Caribbean country.

Showcasing performances from Los Angeles, New York and  London, the telethon will be broadcast through MTV networks  available in 640 million homes worldwide, including for the  first time China’s MTV channel, as well as audiences through  other major networks such as CNN.

The event will also be streamed live on websites including  YouTube, Hulu and MySpace and through mobile phone carriers,  raising the size of the potential audience.

MTV, the show’s co-producer, said the broad collaboration  would make it the most widely distributed telethon in history. Other telethons and concert fundraisers have claimed huge  audiences and brought in millions in relief money.

The Live Aid concert in 1985, to raise funds for famine  relief in Ethiopia, reached an estimated 1.5 billion people at  a time before widespread Internet and mobile phone use.

The London performance of the Haiti benefit will feature  Coldplay plus a group performance by Bono and U2 guitarist The  Edge along with Jay-Z and singer Rihanna.

The Edge, Bono and Jay-Z have teamed up to record a song to  benefit Haiti, MTV said.

Clooney will host the event from Los Angeles with  performances by Alicia Keys, Christina Aguilera, Justin  Timberlake, Taylor Swift and a group jam by Keith Urban, Kid  Rock and Sheryl Crow.

In New York, Haiti-born singer Wyclef Jean will be joined  by Bruce Springsteen, Jennifer Hudson, Mary J. Blige, Shakira  and Sting.
