Will.i.am worked on "secret" Michael Jackson album before pop king's death

Is there a secret Michael Jackson album out there?

According to Black Eyed Peas front man Will.i.am there is.

He told Britain's Daily Mirror Newspaper “It was going to be out of this world. It’s something Michael has never done before – a dance music album. I was very proud of it. But he was very protective and kept it under lock and key."

The "Heartbreaker" producer and songwriter claims to have spent a year with Jackson in Ireland producing the album and says that Jackson insited on keeping every demo and every scrap of work on the album locked away.

The B.E.P. frontman also said he had heard rumours Michael was planning to ask the Black Eyed Peas to open his comeback shows at London's O2 Arena next month.

It has been confirmed over 750,000 fans with tickets for the 50 sold-out London shows will be able to claim a full refund.

They will also be offered the opportunity to donate their ticket money to get a holographic souvenir ticket for the show, which shows Michael dancing across it.

Michael Jackson passed away aged 50, after ingesting a cocktail of prescription drugs at his rented home in Los Angeles.
