Mariah Carey unsure if Nick Cannon is in her docuseries

Pop star Mariah Carey has no idea if her ex-husband Nick Cannon will make an appearance on her forthcoming docuseries "Mariah's World".

The "Without You" hitmaker, who has five-year-old twins Moroccan and Monroe with the "America's Got Talent" host, has admitted she has no idea what will be on the show when it airs on December 4, reported Female First.

The 46-year-old singer attended the Television Critics Association press tour in Los Angeles and when a reporter assumed he would be making an appearance she corrected them.

Carey, who is currently planning her wedding to Australian billionaire James Packer, said, "I didn't say that, darling. I said he came around - I don't know what makes final cut.
