Mariah Canceling Left and Right

Mariah Carey must be feeling some kinda heat these days. And I don't mean in the sack with church-suit-wearin' Nick Cannon either (pointing at you, Eminem).

The singer canceled her August 28^th Today Show concert and will now be replaced by Miley (I need a gum transplant) Cyrus. Carey also canceled an appearance on next month's MTV Video Music Awards and she canned her "VH1 Storytellers" show. She's even delayed her acceptance of her star on the Walk of Fame in Hollywood.

There's word her album, Memoirs of an Imperfect Angel, may be pushed back…again. It's supposed to be released September 15^th.

So this is what Eminem was talking about huh? Ending careers!?! Poor Mimi.
