End of the road for Mariah Carey and Nick Cannon?

US singer-songwriter Mariah Carey and comedian Nick Cannon, who have been married for six years, are "living separately," multiple sources revealed to Page Six.

"He hasn’t been staying at their home..he’s been living out of hotels. They’re fighting a lot," one music scene insider said.

Carey hasn't posted any lovey dovey couple photos (which she is fond of doing) of her and Cannon in a couple of months

This last family portrait was posted about 2 months ago.

Earlier this year, Cannon, 33, hosted pool parties in Las Vegas where the Heartbreaker singer, 44, had reportedly dispatched security to keep watch over her husband.

The source also revealed that Carey has suspected her husband has been cheating.

"The security guard wasn’t there to keep the girls away from him...It was to keep him away from the girls," a source said.

To add to the whispers of a split, Radar Online reported that the couple, who have two children together, are selling a mansion they own in Bel Air, Los Angeles.

Another one bites the dust.
