Christina Aguilera plans to sing in a show honoring the late, great Michael Jackson.

Scheduled for October in Wales, "Michael Forever — The Tribute Concert" will include members of the Jackson family, Cee Lo Green, Leona Lewis and the band Alien Ant Farm, which is known for its cover of Jackson's song "Smooth Criminal."

The announcement, made by the concert’s organizers on Thursday, came after more than two weeks of silence about performers for the Oct. 8 show at Millennium Stadium in Cardiff.

While the event is endorsed by the singer's mother and some of his siblings, brothers Randy and Jermaine Jackson have protested its timing, since the concert is scheduled during the trial of a doctor charged in Jackson's death.

The singer's estate is also not affiliated with the concert.
