The couple are currently on a break after a fight in Greece one month ago and TMZ claims James did not approve of Mariah's friendship with Brian Tanaka, who has worked for her for years.

According to the website, James and Brian had a heated row in Las Vegas in June, where Mariah was performing.

However, there is no suggestion that the relationship between Brian and Mariah is anything more than friendship.

Mariah and James are currently trying to work things out after their blowup in Greece.

Her representative said in a statement: "Mariah and James had a fight in Greece, and have not seen each other since. [The fight was not due to] any cheating allegations or excessive spending. They are trying to work it out. Right now, they're not sure if they will stay together. They are discussing it."

The statement came after it was claimed that the billionaire businessman has allegedly called time on his engagement to the 46-year-old singer because she became obsessed with her reality television show 'Mariah's World', and was "willing to expose their lives to the world" in a way he wasn't comfortable with.

A source claimed: "It's all over. James had huge reservations about Mariah's new reality TV show and the fact that she was willing to expose their lives to the world."

Another source alleged that James was tired of the 'Without You' hitmaker's "extravagant spending".

The insider added: "James is very generous, but Mariah takes it to the next level."

And the 49-year-old mogul - who has been in a relationship with the 'Touch My Body' singer since June 2015 - has reportedly even let Mariah keep the lavish $10 million engagement ring he gave to her when he proposed in January.

It was also claimed that problems surfaced when the chart-topping singer didn't attend a birthday party for James' sister.

The source said: "When she refused to come to Australia for [Packer's sister's] birthday party it created a lot of tension in the family. James' tight circle of friends never really thought they would marry."
