Mariah Flashed Her New $7.5m Diamond Sparkler As She And James Celebrated Their Engagement - See How Ex Nick Cannon Congratulates Her Pretends To Be Heartsick In Funny Snap

This smitten couple could be in for a long engagement as it's been reported neither of them are formally divorced from their former spouses.
  

It's thought financial-settlement issues have delayed the process for Mariah and Nick, despite arranging a pre-nup, while James and ex-wife Erica Packer's settlement has been plagued by stipulations in Australian law, Mail Online has contacted Mariah's, Nick's and James' management for clarification. 

And with the Australian casino businessman worth an estimated $4.5 billion in US dollars, he's definitely someone to have as a friend.

Mariah, 45, has been on cloud nine since James, 47, swept her off her feet less than a year ago.

The songbird's engagement ring is a .35 carat diamond sparkler estimated to be worth approximately $7.5 million.

The designer of the ring, Wildred Rosado, told Vogue he went to great lengths to create the perfect ring that would express James' total love and adoration for Mariah.

'I took the standards super high, and I wanted to create a ring that could not be measured up to,' the designer said.

'I really wanted to create something for her that was about new beginnings,' Rosado said of the Butterfly singer. 'She obviously has a strong point of view about what she likes.'

Mariah and James went public with their romance in June of last year, and spent part of the summer cruising along the Italian Riviera on his yacht.

The 35-year-old America's Got Talent host enjoyed his own moment in the spotlight by posting a silly Instagram on Friday in the wake of Mariah's engagement to billionaire James Packer.

His own marriage to Mariah Carey ended last year, but at least Nick Cannon has a sense of humour about it.

But it was all staged fun with Hart's help, judging by Nick's caring message intended for his ex.

 

Nick was seen in a hospital bed clothed in one of those unsightly hospital gowns with eyes closed as though prostrate with heartsickness, as his pal Kevin Hart hovered over him with a worried expression.

'Ha! This made me laugh out loud for real!!! HILARIOUS! #AllLove,' Nick wrote alongside the humourous snap.

He then added on a sincere note: 'Congrats to @MariahCarey and James! May God Bless Your Future Union... #GreatPeople #GreatCouple'

Nick - who shares two children with Mariah, four-year-old twins Moroccan and Monroe - seemed mighty upbeat, proof that being positive can conquer anything.

Talk of engagement spread like wildfire on Thursday, with representatives for the singer confirming the news to Daily Mail Australia, saying: 'Yes, the couples were engaged tonight in New York.'

The couple celebrated their new relationship status at an engagement party at Eleven Madison Park on Thursday.
