The singer was expected to have the record in shops on November 18, but it is believed that her work on two movies - Cadillac Records and Obsessed - has caused a delay.
A source told the New York Daily News that it is imperative that the LP is released by the end of the year.
"The album is not going to be completed by November 18. But she's got to get it out early in the fourth quarter, when there's so much competition among artists," said the insider.
