Mariah has had several closed door meetings with divorce lawyers,''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.'
'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.'They're not living together because they can't stand each other.''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.'
Mariah and Nick also share a $5 million private jet and a cavalcade of cars - including a $400,000 Lamborghini.
The duo's last red carpet appearance was at the SAG Awards in January, and their last public sighting was at a February 12 MTV event.
