R&B diva Mariah Carey is reportedly on the verge of hitting the open market as breakup rumors with Hollywood actor Nick Cannon have surfaced online this week.

According to reports, Cannon and Carey have been living apart for the past few months.

Mariah Carey and Nick Cannon separated back in May — and are living apart … and we’re told divorce lawyers have been negotiating a property settlement and custody agreement for months and the divorce is “a done deal.” Sources connected with the couple tell TMZ … Mariah and Nick have been living in separate houses in NYC since May. He sees the kids but that’s the extent of their contact. (TMZ)

Reports also claim Carey’s issues stem from Nick not being a big family man.

Our sources say Mariah feels Nick has abandoned her by taking every gig that’s on the table … when they don’t need the money. She’s especially angry because it keeps him away from their kids. For Nick’s part … we’re told he feels Mariah has become impossible because she surrounds herself with “yes men.” He says she can’t handle it when he dares to disagree with her. (TMZ)

Cannon confessing to his past romantic flings also reportedly played a big role in the split.

Mariah reportedly got miffed after he revealed on the Big Boy Radio Show that he had slept with Kim Kardashian and then to Howard Stern that Mariah refused to have sex with him until they got married. These confessions — added to his workaholic nature — reportedly put too much strain on their union. Mariah, 45, and Nick, 33, have been married for six years after tying the knot on April 30, 2008.

Music icon Jermaine Dupri recently broke unexpected news of cutting business ties with Carey.

“I’m a very hands-on person when it comes to my work,” JD said. “I put my all into every project. But when I’m not allowed to do what I do, then I know it’s time for me to move on. Mariah and I enjoy working together and will continue to make great music together in the future.” (Billboard)
