Lionel Richie and Quincy Jones are planning a 25th anniversary re-recording of We Are The World.
The Hollywood Reporter says that Usher, Natalie Cole and John Legend have been invited to take part in the supergroup single, which was originally released in 1985 after the success of Band Aid in the UK.
Lionel and Quincy, who co-wrote and co-produced the song respectively with Michael Jackson, hope an abundance of stars will take part in the celebration on February 1 - a day after the Grammy Awards ceremony, which will include a tribute to the late King of Pop.
All the Grammy nominees and participants will also be asked to take part, the Hollywood Reporter said.
The event was originally due to take part on January 28 but the date changed in the wake of the Haiti earthquake - and now all proceeds will go towards the relief fund.
