Nick Cannon has signed and sealed a deal to write a tell-all book about his marriage to Mariah Carey - and she is furious about him betraying her.
Mariah rejected Nick's numerous demands for a $30 million divorce settlement so now he's writing the book — saying he plans get his payday for being married to her one way or another - and there is nothing she can do about it because he already signed the deal last week with major publishing company Simon and Schuster.
Simon & Schuster has confirmed to Daily Mail Online that the book is being published by Gallery Books, an imprint of the high-powered publisher.
'Nick says he is going to tell the world about Mariah's drug use, her strange eating habits, psychosis, what she has said about other artists, her sexual proclivities and her parenting skills. It which will really be hurtful,' the insider continued.
'And Nick is also going to explain why he thinks he should have full custody of the twins. Mariah has admitted she never wanted children and Nick is going to tell the world why she felt that way.
'If Nick was not willing to spill all of their nasty and salacious secrets he would not have gotten a book deal. So obviously, Simon and Schuster feel this is going to be a blockbuster and they signed him up.'
'Mariah was willing to give Nick $10 million but he said 'hell no' and demanded $30,' a family friend tells the Daily Mail exclusively.
But Nick insisted he needs and deserves more than what they originally talked about, but Mariah wouldn't budge.
