Just days before they were due to play, The Black Eyed Peas have pulled out of Cardiff’s Michael Jackson tribute concert.

The I Gotta Feeling megastars were one of the biggest names on the line up for Saturday’s event.

But they pulled out, just a week after agreeing to perform, because of “unavoidable circumstances”.

The CEO of organisers Global Live Events, Chris Hunt, said: “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 event is really getting into gear and is going to be a fantastic evening for all".

Jamie Foxx to host Michael Jackson tribute show

Christina Aguilera, Gladys Knight and Smokey Robinson will be performing The Michael Forever Tribute Concert, held at Cardiff’s Millennium Stadium.

Leona Lewis, JLS and Diversity will also play the massive tribute gig, which will be hosted by Fearne Cotton and Oscar-winning actor Jamie Foxx.

Jackson’s brothers Marlon, Tito and Jackie, and his sister La Toya will also perform at the event, despite criticism from fans other brothers Jermaine and Randy.

But Tito defended their decision to perform at the memorial concert, which takes place during the trial of Jackson’s doctor, Conrad Murray.

He said: “The whole thing is…to honour him as a brother and as an entertainer and as a person who dedicated his life to others."

Murray has pleaded not guilty to the claim that he caused Jackson’s death by giving him the powerful drug, Propofol to help him sleep.

Saturday’s tribute show will raise money for Aids Project Los Angeles and two more charities, which haven’t been determined yet.

A documentary about the star, called Michael Jackson: The Life of an Icon, will also have its world premiere in London on November 2 at Empire Leicester Square. It will be out on DVD two days before.
