Kim Kardashian sex confession to blame for Mariah Carey and Nick Cannon's split?

Mariah Carey's husband Nick Cannon has confirmed reports their six-year marriage is on the rocks — and Kim Kardashian may be to blame.

America's Got Talent host Nick addressed this week's reports the superstar couple are heading for a divorce, telling The Insider: "There is trouble in paradise. We have been living separate houses for a few months."

One of the triggers was Nick's on-camera revelation to radio host Big Boy in March about his past sexual conquests, including Kim Kardashian, who he dated from September 2006 to January 2007. Watch above to see Nick's scandalous sex confession...

"That made Mariah insane and humiliated," sources told TMZ. "She tore into Nick for weeks."

Mariah is reportedly worried about Nick's "wandering eye", a source told Page Six this week.

Earlier this month, the pair enlisted lawyers to talk property and custody agreements over their three-year-old twins, Moroccan and Monroe, according to TMZ. The couple have put their Bahamas and Bel Air homes on the market.

While Nick is yet to confirm the divorce, he added: "My main focus is my kids." Sounds like it's a done deal...

Mariah, 44, and Nick, 33, wed in April 2008 and renewed their vows in Paris in 2012 and in Disneyland in 2013.
