– They've been living separately for a while, and now Mariah Carey and Nick Cannon are making the split official, reports People. Cannon filed divorce papers last month, and TMZ reports that the couple has worked out a deal to split their property. (They've also got 3-year-old twins.) The website takes note of an unusual feature of their prenup: If Cannon violates a confidentiality clause and talks about their marriage, he has to pay up $250,000; if Carey talks, she has to pay $500,000. The reason is simple: She's got a lot more money than he does, and an upcoming artist-in-residence gig in Vegas will only widen the gap.
