Mariah Carey's Missing In Action

Mariah Carey's fans have been wondering if all is well in the butterfly-filled world of the singing chanteuse after she inexplicably canceled a few appearances and pushed back the release date of her latest album, Memoirs of an Imperfect Angel.
Carey was scheduled to receive a star on the Hollywood
Walk of Fame, perform on the Today Show and tape an
episode of VH1's Storytellers—all of which have been "postponed" indefinitely.

Although Mimi excused herself after her lackluster performance at Michael Jackson's memorial service due to overwhelming emotions, her follow-up gig on hubby Nick Cannon's show, America's Got Talent was equally as terrible. Rumors have been flying that her new album may not meet the chart-topping success her past work, and apparently, Whitney Houston's highly anticipated re-entry into the music world isn't doing anything to calm Mariah's nerves. 

Regardless, Carey's rep, Cindi Berger, insists that there is nothing wrong with the singer, telling people.com, "These dates have been postponed and not canceled. Record release dates change all the time."

"It's nothing unusual and it doesn't signal anything. There are a lot of moving parts to Mariah's professional life," Berger confirms. "She's making sure the record is how she wants it to be and its no big deal."
Memoirs of an Imperfect Angel is now scheduled to hit shelves September 29th.
