Nick Cannon, Mariah Carey heading for split?

'America's Got Talent' host Nick Cannon and his pop star wife Mariah Carey are reportedly heading for a split and have been living separately.
The 33-year-old TV host, who married Carey in 2008 and has four-year-old twins with her, is currently staying at a hotel following a lot of tiffs, reported the New York Post.
"He hasn't been staying at their home. He's been living out of hotels. They're fighting a lot," a source said.
Carey, 45, is said to have grown increasingly suspicious of Cannon and has reportedly hired security to keep him away from women when he hosted pool 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," the source said.
