The Australian billionaire, 50, has broken his silence on his whirlwind engagement to the 47-year-old superstar - which he called off in October 2016 - and confessed the romance was a "mistake" for them both.

The father-of-three said: "I was at a low point in my personal life. She was kind, exciting and fun. Mariah is a woman of substance. But it was a mistake for her and a mistake for me."

James also admitted that his "biggest regret" was getting divorced from his ex-wife Erica Baxter, who later dated chart topper Seal for 12 months.

He added in an interview with The Australian: "It is my biggest regret that I let my marriage to Erica fail. It is what it is and she is doing an incredible job with the kids and we are in a great place."

Mariah was left devastated when James ended their nine-month romance this time last year and she reportedly blamed Scientology for the split when their engagement was suddenly called off.

Insiders claimed at the time that she believed James - who was a Scientologist between 2002 and 2006 - had been influenced by his business manager and former Church of Scientology spokesperson Tommy Davis, who Mariah believed poisoned his mind against her.

James' camp denied Scientology had anything to do with their split and instead, sources claimed he blamed it on Mariah's excessive spending and the drama surrounding her as she filmed her reality show 'Mariah's World'.

The pair were first introduced by mutual friend Brett Ratner at the premiere of Hercules in 2014.

In January 2016, the billionaire got down on one knee and proposed with a jaw-dropping 35-carat diamond engagement ring, which was rumoured to be worth £8million.
