Mariah Carey and Nick Cannon's marriage is reportedly on the rocks.

The couple - who tied the knot two months ago following a whirlwind
six-month romance - are said to already be arguing about Mariah's demanding
behaviour.

A source said: "Nick is basically around to attend to her diva-ish ways.
When they were in Hawaii where Mariah was filming the video for 'I'll Be
Lovin' U', Nick dashed off to buy her gifts at Tiffany and Co. and Louis
Vuitton to keep her happy."



When 39-year-old Mariah injured herself during the shoot, Nick was right by
her side.

The source added to America's OK! magazine: "He helped Mariah out of the
pool. She looked like she was going to cry."

Mariah is also reportedly taking control of 27-year-old Nick's career, and
is keen to promote his musical ability with high-profile performances.

An insider said: "Nick had signed on to perform at a sweet-sixteen party
before he and Mariah got married. But now Mariah needs to oversee and
approve his career moves.

"There are no more silly small-time gigs. She wants him to do big venues and
projects. She definitely wears the pants in the relationship."



Her butterfly ring is available for replacement.



She couldn't stand having a plain ear piece. Check out her new video.
