According to TMZ, Mariah Carey has gagged Nick Cannon — but not in a good way.  He’s not allowed to say a word about their divorce … or else.

Sources close to the couple tells … Nick and Mariah’s lawyers hashed out a confidentiality agreement as part of their divorce … and it’s completely one-sided. 

Nick is banned from saying anything about the split.  If he does, there are severe financial penalties. But Mariah has the right under the agreement to announce the split on her terms.
Nick is clearly following orders

Nick is allowed to say they’re now living separately … which he’s already done.  But he cannot say anything about the divorce.

As TMZ first reported … the divorce is a “done deal” and have been seperated for months… the property settlement and child custody have already been hashed out.
