Carey's marriage 'will last six months'

A friend of Marah Carey does not think that the popstar's marriage to Nick Cannon will last longer than six months.

The couple wed in April after a whirlwind romance, but sources close to the pair believe Cannon will not be able to cope with his wife's diva demands.

Carey's friend told Life And Style Weekly: "I give the marriage six months, tops. I can't see it lasting.

"Nick does whatever Mariah wants him to - he's like her puppy. It seems like he spends more time in the stores with Mariah's credit card than he does with Mariah herself.

"Mariah's assistants and friends call him 'Whipped Nick' behind his back. They have little respect for him because he won't stand up for himself."
