Nick Cannon has bigger issues than beef with Cam’ron these days. His wife Mariah Carey wants out. The Grammy Award winning singer is reportedly ready to call it quits with her rapper husband who put bed rumors last month that they had issues of infidelity. While that may not have been the problem, one source made it clear that they're no longer happy in in paradise.

“Mariah'd cut him loose right now. But she's worried about him making a grab for a huge chunk of her $515 million fortune," one insider told America's OK! Magazine. "Nick feels burned that Mariah is ready to pull the plug. They have a pre-nup, but after Nick tells his side of the story Mariah will most likely settle with him financially and realize her once beautiful marriage has evaporated."

According to the Huffington Post, things went downhill for the couple after the release of Cannon’s album White People Party Music. While promoting the album the America’s Got Talent host made a few comments his wife did not like, that included discussing their sex life and his past relationship with the soon to be Mrs. West. It is said that things are so rocky that the pair didn’t even celebrate their recent sixth wedding anniversary.

“Mariah threw a diva fit and started browbeating Nick about being an absentee, no-good husband. She gave him hell for being immature and accused him of fooling around with other chicks," said the source. "She told him to cancel whatever anniversary plans he'd made."
