Mariah's World has been documenting the superstar's life, her split from fiance James Packer and her new romance with dancer Brian Tanaka since late last year (16) - and Cannon is even featured in one episode.

But, during a chat with radio talk show king Howard Stern on Wednesday (08Feb17), Nick made it clear he doesn't believe anything he sees on TV - and urges fans not to buy into the show either.

"I think the reality show is fake...," he told Stern. "Look, I'm a producer... You can't have a well-lit private conversation. I'm not buying any of that s**t."

And Cannon admits he was more than a little annoyed when a family party turned into a TV shoot without his prior knowledge or consent.

"There was one episode where I was there... It was a party so I showed up to hang out with my kids, and I'm like, 'There's f**king cameras here."

Cannon shares twins Moroccan and Monroe with his ex-wife.
