Billionaire James spoke about his former love of a year-and-a-half during an interview withThe Australian this month

‘She was kind, exciting and fun. Mariah is a woman of substance. She is very bright. But it was a mistake for her and a mistake for me,’ he noted.

He said he met the songstress at a ‘low point’ in his life when debt within his empire was escalating and when he was looking for a way to spend more time in Los Angeles to be close to his children with second wife Erica.

Packer, now 50, said he was also under strain from a painstaking negotiation process with his estranged sister Gretel over how they would divvy up and invest money they had been left by their late father Kerry.
