Nick Cannon and Mariah Carey

Nick Cannon and Mariah Carey

Nick Cannon hopes he and Mariah Carey can both "move forward" in 2015.

The 'America's Got Talent' host, who separated from the 44-year-old singer over the summer after six-years of marriage, insists he will "never say anything negative" about the '#Beautiful' hitmaker, with whom he has three-year-old twins Monroe and Moroccan, following speculation he is planning to write a "diss album" about his estranged wife.

Slamming the rumours on Twitter, he wrote: "I will never say anything negative about @MariahCarey We are forever a family rooted in love.

"I am always an open book but Personal matters are just that 'Personal.' So please respect my family and respect the process."

He later added: "I have no problem being painted as the bad guy. I got tough skin. Keep going! I just pray we ALL can move forward in the new year."

A source close to Mariah - who broke down in tears while performing in New York City earlier this month - recently admitted she is still devastated over her split from Nick, 34, and isn't ready to "give up the idea of a happy family."
