Taylor Swift, Jay-Z join Haiti telethon

Performances will be available for purchase on iTunes

NEW YORK -- The music world's top stars are signing on for Friday's Hope for Haiti telethon.

Bruce Springsteen, Jay-Z, Taylor Swift, Justin Timberlake, Keith Urban and Alicia Keys are just a few of the performers who will be featured, according to MTV Networks, an integral partner in the event.

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

Haiti was devastated and thousands of its citizens killed when an earthquake hit the Caribbean nation last week.

The "Hope for Haiti" benefit will be broadcast from New York, Los Angeles, London and Haiti. It will be televised on all the major networks plus several additional channels.
