quits america's got talent

*Nick Cannon is putting the National Enquirer on notice over an article the publication is preparing to run that could result in the TV host/actor/comedian/rapper filing a slander and defamation lawsuit.

On Tuesday, Cannon posted to Instagram a purported article of unknown origin saying:

“The National Enquirer is preparing an article reporting Nick Cannon has suffered a nervous breakdown and his erratic behavior has given ex-wife Mariah Carey little choice but to petition for custody of their children.”

The alleged article also says Cannon burned bridges with NBC executives on the set of “America’s Got Talent,” which he announced he would be leaving earlier this month. As we reported, in a Facebook post, Cannon stated his departure was over a racial joke he made in a recent Showtime stand-up special that did not sit well with NBC.

“I will not be silenced,” he wrote.

The National Enquirer piece allegedly also cites a new lawsuit reported on Monday by TMZ, wherein a man claims Cannon stole his app idea to build his own talent search app N’credible and is seeking $1.75 million in damages.

Cannon slapped back at the National Enquirer for noting his children – twins Monroe and Moroccan, whom he shares with Carey – saying:

“Only Evil operates in this manner. What is the purpose? Except to exemplify pure immoral wickedness. If you report these lies expect a slander and defamation lawsuit.”

Last week, as we also reported, Page 6 published a story that also claimed insiders are concerned over Cannon’s health, citing his recent decision to leave ICM Partners for CAA. Cannon also shared that story on Instagram and responded with:

“Funny how when a man stands up for himself the media fears his mental health!”
