*The Black Eyed Peas will not be a part of the upcoming Michael Jackson tribute concert in Wales after all.

The group is citing “unavoidable circumstances” for its decision to pull out of the event scheduled for Oct. 8 in Cardiff, reports the BBC.

Chris Hunt, chief executive officer of the promotion company behind the gig, Global Live Events, says, “It is with regret that we announce the removal of Black Eyed Peas from the Michael Forever bill, but I look forward to a great night with other earth shattering artists.”

The concert at Cardiff’s Millennium Stadium will feature stars including Christina Aguilera, Leona Lewis, Ne-Yo and Cee Lo Green. Jamie Foxx will host.
