Lack of "motivation" means he wont be releasing it till at least 2010

Dr Dre has admitted that his long-awaited new album ‘Detox’ won’t be released until at least 2010.

The rapper, who previewed a track from the album earlier this year on a Dr Pepper advert, has blamed a lack of “motivation” for the delays.

“Hopefully, I’ll get it done at the end of this year, and we can hear it next year,” he told ABC News.

The album, which was originally due in 2004, has been hit by persistent delays, and was last scheduled to be released this year.

The record will be the eventual follow-up to Dr Dre‘s critically acclaimed album ‘2001’, which was released in 1999.

The number of postponed release dates have been attributed to his production work with artists including Eminem and 50 Cent.
