The 'America's Got Talent' host split from the 'Hero' singer - who whom he has twins Moroccan and Monroe, five - in August 2014 and he filed for divorce later that year.

Though they struck a property settlement and agreed to joint custody of their twins in December 2014, it was recently claimed Nick has repeatedly declined to sign the paperwork to make the divorce official, but he insists that isn't the case.

He told 'Extra': "There's nothing to tell... me and Mariah get along great, and it's a process, nobody is holding nothing up. Why would I hold it up? I want her to be happy.

"She is such a beautiful spirit, and we put the kids first."

Mariah got engaged to Australian billionaire James Packer in January and recently admitted "the goal" is for them to tie the knot later this year.

However, she added: "There's a lot on my plate."

When news broke in January that the Australian businessman had popped the question to the 'We Belong Together' singer, Nick was quick to congratulate them.

He tweeted: "Congrats to @MariahCarey and James! May God Bless Your Future Union... #GreatPeople #GreatCouple. (sic)"

And Nick also poked fun at his own reaction to the news, sharing a picture from his television show 'Real Husbands of Hollywood', where he is lying in a hospital bed with Kevin Hart looking at him worried, with the caption reading, "It's just a ring Nick ..."

Adding his own caption to the picture, he shared: "Ha! This made me laugh out loud for real!!! HILARIOUS! #AllLove (sic)"

Meanwhile, Nick previously insisted Mariah, 46, will always be the "love of [his] life".

He said: "It's one of those things, I'm a hopeless romantic too.

Through this learning process, you never say never. To me one thing I know, that will always be the love of my life, always be my family and that's never going to change.

"It's extremely disappointing when you see that people just want to perpetuate negativity when there is no negativity even involved."
