Mariah Carey has postponed the release of her new album for a second time - fans will have to wait another six weeks to hear her "Memoirs Of An Imperfect Angel".

The singer prompted speculation of a delay on Wednesday when she pulled out of a scheduled televised concert in New York on August 28, when she was expected to showcase tracks from the album. Miley Cyrus will replace her.

On Thursday a statement from her record company confirmed the release has been pushed back to September 29.

It reads, "Mariah is putting the finishing touches on her newest album, 'Memoirs of an Imperfect Angel', and we have shifted all of our TV and promo appearances to coincide with the new release date of September 29th. We can't wait for the fans to hear the new album."

It's not the first time Carey has delayed the release; it was initially slated to hit stores on August but was pushed back to mid September in an announcement last month.
