Christina Aguilera has signed on to perform at the "Michael Forever - The Tribute Concert" in Wales, according to organizers.
She'll be joined by members of the Jackson family, Cee Lo Green, Leona Lewis and the band Alien Ant Farm.
The concert will be held in October, and it's endorsed by most of Jackson's family.
Randy and Jermaine Jackson oppose the timing of the concert, because it coincides with the trial of Conrad Murray, who's charged in Jackson's death.
