*Jay-Z and Alicia Keys are among the performers newly-added to Friday’s “Hope for Haiti” telethon organized by George Clooney.

“Hope For Haiti Now: A Global Benefit for Earthquake Relief” will be an international event to benefit the devastated Caribbean nation in the wake of the deadly 7.0 earthquake that hit last week.

Bruce Springsteen, Taylor Swift, Justin Timberlake and Keith Urban were also added to the lineup, according to MTV Networks, an integral partner in the two-hour telecast.

Haitian native Wyclef Jean will anchor the show from New York, while Clooney will do so from Los Angeles. CNN’s Anderson Cooper will report from Haiti.

London has also been added to the lineup, and that’s where Jay-Z will take the stage, along with Bono, The Edge and Rihanna in a special joint performance. Coldplay is also to perform from London.

In New York, Springsteen will perform, along with Jennifer Hudson, Mary J. Blige, Shakira, Jean and Sting. In Los Angeles, Swift is to perform, and Urban, Kid Rock and Sheryl Crow plan a collaboration. Also performing in Los Angeles is Timberlake, Dave Matthews, John Legend, and Stevie Wonder.

People can purchase the night’s performances for 99 cents each through iTunes beginning Saturday. A statement released Tuesday says all proceeds will go to Haiti relief.

As previously reported, the “Hope for Haiti” benefit will be televised on all the major networks at 8 p.m. EST, as well as MTV, VH1, CMT, BET, PBS, CNN, Bravo, and a host of other networks. In addition, the telethon will be streamed live on Web sites including YouTube, MySpace and AOL.

The funds raised from the telethon will be donated to several relief organizations, including UNICEF, Oxfam America and Partners in Health.
