Mariah Carey and Nick Cannon are headed for a split, sources reveal to TMZ.  The couple, who married in a whirlwind ceremony six years ago after less than a month of dating, are living separately and will soon go public with their divorce news, the source allegedly says.
One possible cause of tension between Carey, 45, and Cannon, 33, is that the R&B diva doesn't trust her husband to stay away from other women. According to reports, when the Real Husbands of Hollywood star hosted pool parties in Las Vegas earlier this year, Carey hired a security guard to keep watch over her husband. “The security guard wasn’t there to keep the girls away from him,” said our source. “It was to keep him away from the girls.”
Additionally, gossip columns pointed out that Carey and Cannon haven't been photograhed together in weeks, and the usually affectionate couple haven't been featured in each other's social media feeds in quite a while. 
The couple, who tied the knot in 2008, have two children, twins Morroccan and Monroe, that they dubbed "dem babies."
