Believe it or not, there may already be problems with Mariah Carey and Nick Cannon's fantasy land marriage.

I love Mariah, but I feel like she's made a HUGE mistake!

HollyScoop is reporting that there may be some trouble brewing...

"...rumor has it Nick is over Mariah's diva ways. What on earth did he think he was getting into?

Every time we turn around he's playing personal assistant to his new wife, be it on the set of her music video or running countless errands around town.

Mariah is also basically taking over Nick's career, letting him only play major venues, and overseeing his career moves."

If Nick Cannon has any sense, he'll listen to what Mariah has to say. Girl knows what she's doing. He'll probably fuck it all up and ask for alimony soon.
