Trouble in Nick-And-Mariahdise? According to "sources," the newlyweds are never going to last. Did we need an anonymous source to tell us that?

“I give the marriage six months, tops,” said a source close to the singer. “I can’t see it lasting.”

The insider claims that the reason behind that gloom-and-doom prediction is Nick’s need to do everything for his diva bride. While Mariah likes being waited on hand and foot, that routine won’t work in the long run.

“Nick does whatever Mariah wants him to — he’s like her puppy,” the insider continued. “It seems like Nick spends more time in the stores with Mariah’s credit card than he does with Mariah herself.”

Oh. I thought our reliable source was going to tell us that they don't get along, or that they only married because the sex was good, or that it was all a publicity stunt. But Nick Cannon paying excessive amounts of attention to his more famous, more rich wife? Sounds like a match made in heaven for both of them. [MSNBC]
