J.Lo and Manager -- Who Fired Who?

It's all over between Jennifer Lopez and her manager, music biz legend Irving Azoff. Our Azoff sources tell TMZ he just fired J.Lo for being "unprofessional" and for allowing hubby Marc Anthony to "constantly meddle."

The mama-to-be got a letter from Azoff last week, we're told, detailing "in blunt terms" why he was ditching her as a client after less than a year. There was also a "heated phone call" last week between Jenny's handlers and Azoff.

But Lopez's rep tells TMZ stories of a bitter split are completely untrue. The rep says "she let him go on Friday with no drama." As for the letter? Jen's camp has no knowledge of it.

Stay tuned ...
