The New York Post has no chill. After posting umpteenth stories about Beyonce and Jay Z's purported crumbling marriage, it looks like Mariah Carey and Nick Cannon are next.

The newspaper reports that Mimi and Nick are headed to splitsville. Apparently, the couple are "living separately" because they've been arguing a lot lately.

"[Cannon] hasn’t been staying at their home," said an insider. “He’s been living out of hotels. They’re fighting a lot."

Another source told the newspaper that Carey suspects Cannon of infidelity. So much so, that the R&B singer hired a security guard to look after her hubby while he was hosting parties in Las Vegas earlier this year. “The security guard wasn’t there to keep the girls away from him. It was to keep him away from the girls," said the source.

Carey also didn’t want Cannon drinking while at his Vegas gigs because she felt he “gets in trouble when he drinks,” the source added.

Carey and Cannon have been married for six years and are the proud parents of three-year-old twins, Monroe and Moroccan.

A rep for Carey had no comment on the matter.

In the meantime, the '#Beautiful' singer is heading overseas to launch her The Elusive Chanteuse Show in Japan. The trek kicks off Oct. 4 in Tokyo and continues across Asia before wrapping up on Oct. 28 in Manila, Philippines. U.S. dates are expected to be announced in the coming weeks.
