A few weeks back, we noted that the latest releases from a handful of musical megastars like Lil Wayne and P. Diddy had been pushed back more times this summer than we care to count. Also included on that list was Mariah Carey, whose Memoirs of an Imperfect Angel had been delayed from August 25 to September 15. Well, today brings news that Mimi needs another two weeks to work on the project: The record will now come out on September 29. [Mariah Carey]
