Nick Cannon is said to have asked Mariah Carey to cough up $30 million following their split last year, now set to pen a tell-all book about their marriage after she rejected the request.

Full story below…

The pair split following the release of the singer’s last studio album ‘Me.I Am Mariah…The Elusive Chanteuse’, ending their marriage after tying the knot in 2008.

Now, Nick is said to have inked a deal to publish a tell-all book detailing his time with the ‘Mine Again’ singer after he learned she refused to pay him the amount he requested.

Unfortunately, “sources” now claim that Cannon is to expose Carey’s alleged drug use, yoyo dieting and “sexual proclivities” in the book whose release has been confirmed by the publishing company Simon & Schulster.
