Mariah Carey and Nick Cannon are on “trial separation” and are possibly on their way to a final split according to reports. Sources claim that the pop diva has been in serious closed-door discussions with her divorce lawyers. Cannon, on the other hand, is not actively seeking counsel.

“But Nick’s being more passive. He’s less inclined to pull the trigger, perhaps because of the kids. He’ll definitely wait for Mariah to file for divorce, but he won’t go down without a fight. He wants a chunk of her $500 million fortune.”

The source added: “Nick’s sensible and realizes that the twins would have a more stable existence if Mariah had full custody. But he wants generous visitation rights.”

The couple caused a stir when they married in 2008 after a two-month whirlwind courtship. She was then 39 and he was 27. Carey gave birth to their children, fraternal twins Monroe and Moroccan Scott, in 2011.

They used to be very public about their affections for each other, with Cannon posting numerous over-the-top tweets of endearment. Their followers, however, have noticed they have gone cold on social media in the past months.

HAPPY I LOVE YOU DAY to my wife! Every 30th is I love you day!

Reports of jealousy and suspicion further confirm that the couple are heading separate ways. Carey was apparently so suspect of Cannon’s nightclub hosting gigs that she hired a security guard “…to keep him away from the girls”

Insiders claim it won’t be long before they officially announce their break up. “When they spend time together these days, it’s just bickering. Mariah seemed to give up on the marriage earlier this year. And now he’s checked out too.”

The couple had been living apart for most of this year, using home improvements as their cover. They are renovating their $10 million loft in Tribeca and have put their Bel Air mansion up for sale.

The America’s Got Talent host is apparently staying at his grandparents’ house in the meantime.

He was spotted Monday night at Tao Downtown and was seemingly all smiles despite the rumors. He was there to celebrate a birthday party for Sujit Kundu, the founder of DJ management firm SKAM artist.
