R&B diva Mariah Carey's remix album 'Angels Advocate' is being delayed. The record revisits and remixes Carey's 2009 release, 'Memoirs of an Imperfect Angel,' featuring guest appearances by Swizz Beatz, Trey Songz, R.Kelly,T-Pain, Gucci Mane, OJ Da Juiceman and more, alongside production work by Tricky Stewart and the Dream.

The album was initially slated for a Feb. 23 release, but has since been pushed to March 9, for undisclosed reasons.

'Memoirs' producer Tricky Stewart discussed the album last year, saying "I'm gonna do a remix to 'I Want to Know What Love Is' myself. I'mma raise the tempo up. I'mma try to make it into something else. ... Once I get the beat and if it calls for the right person, I can get anybody on the phone I want to right now, so I will be using my Rolodex for that."

Carey is currently promoting the album on her Angels Advocate Tour, which ends in Las Vegas on Feb. 27.

She was also recently honored with a People's Choice award for Favorite R&B Artist, and received the Breakthrough Actress award at the Palm Springs International Film Festival for her role in 'Precious.'
