The end may be near for MARIAH CAREY & NICK CANNON’s marriage – report.

Mariah  and comedian/rapper Nick  are headed for a split and “living separately” reportedly after  she hired security to keep him away from other women, The New York Post's Page Six reported.

Sources say Carey and the “America’s Got Talent” host are separating after six years of marriage.

 “He hasn’t been staying at their home,” a music insider told the Gotham tab. “He’s been living out of hotels. They’re fighting a lot.”

Another source said Carey has suspected Cannon of cheating.

When Cannon hosted bikini-babe pool parties in  Vegas earlier this year, the suspicious diva sent a security guard to keep eyeballs peeled “to keep (Nick) away from the girls”.

Reportedly, Mariah wanted :”eyes on” because she doesn’t want her hubby of 8 years boozing at Vegas gigs because, the Post alleged, “gets in trouble when he drinks.”

Reps for the couple didn’t respond to media queries.
