Others confirmed for the event include Sting, Christina Aguilera, Justin Timberlake and Alicia Keys. The event is being organised by George Clooney who said that more than over 40 artists are expected to attend the show.
The aim of the concert, Clooney explained, is "to show the people of Haiti that the whole world is paying attention".
The benefit, likely to be broadcast on a dozen American TV networks, will be hosted by Clooney and the Haitian-born perfomer Wyclef Jean.
According to actor Mark Wahlberg: "Haiti has been one of the poorest countries in the world for such a long time. And it's important for people to continue to help and change that."
The Hope For Haiti event will benefit the Red Cross, Unicef, Oxfam America, Partners in Health and Yclef Jean's Yele Haiti Foundation.
Songs from participating artists will be available on iTunes, with proceeds going towards the fund.
