The release of Mariah Carey’s upcoming 12th studio album has been delayed for a second time.

Memoirs Of An Imperfect Angel, which was originally scheduled for release on August 29 and then September 15, will now arrive two weeks later on September 29.

Mariah has also pulled out of a string of live performances scheduled to coincide with the album’s original release date, including appearances on VH1 Storytellers, TODAY, the MTV Video Music Awards, and her Hollywood Walk of Fame star ceremony.

A source at Def Jam tells Reuters that the star has returned to the studio to record additional songs for the album.
