Christina Aguilera, Leona Lewis, & Cee Lo to Perform at Michael Jackson Tribute

Christina Aguilera, Leona Lewis, and Cee Lo Green will honor Michael Jackson by taking part in a tribute concert in October.

The singing superstars join Smokey Robinson, JLS, Alien Ant Farm, and Craig David as performers for “Michael Forever: The Tribute Concert,” promoters told CNN. The show, sanctioned by Michael’s mother Katherine Jackson, will take place on October 8 in Cardiff, Wales, with members of the Jackson family taking the stage including the King of Pop’s brothers and 3T, which consists of Tito Jackson’s three sons.

Seventy-five thousand people are expected to attend the four-hour-plus concert at Wales Millennium Stadium. The singers have been asked to perform one or two of their favorite MJ songs.

Fans can start registering their interest for tickets online beginning Thursday. A lottery will be held to determine who will be able to purchase tickets.

More performers will be announced in the coming days. TMZ reported that Kanye West, Jay-Z, and Chris Brown all received invitations from Katherine Jackson, but their participation has not been confirmed.
