She explained: “If it was a relationship that mattered, it’s in the book. If not, it didn’t occur.

“We didn’t have a physical relationship, to be honest with you.”

The former pair began their relationship in 2015 and were engaged nine months later.

However, the two would part ways just nine months later.

The Grammy winner, 50, isn’t the only one who opened up about their relationship, as the businessman wrote about Mariah in his 2018 memoir The Price Of Fortune: The Untold Story Of Being James Packer.

In the book, James wrote that he had “become toxic” by the time the split had occurred.

He added: “Wherever we went we were on the top table and that was because of her, not me. She was kind and she took an interest in my life.”

Long before James, Mariah was married to music executive Tommy Mottola from 1993 to 1998, who is in the hitmaker’s book.

Former baseball player Derek Jeter also found himself dating Mariah, a short relationship that she detailed in her tell-all.

She wrote: “Everything was so new and sweet, down to the smooth texture of his honey-dipped skin. It was how it was supposed to feel.”

Mariah also wrote how Derek was only the “second person I had ever slept with.”

She explained in the book: “Just like his position on the team, our relationship was a short stop in my life.

“It was a very critical transition for me, and maybe a dream come true, or maybe an accomplishment, for him. I don’t know.

“Very soon we weren’t meant for the long run. For one, there’s a great gulf between athletes and artists, and honestly it’s hard for two stars from any industry to make it work.”

The ex-Yankee, whom she began a relationship with while still married to Tommy, was “a love in my life, not of my life,” Mariah explained.

In 2008, Mariah married actor Nick Cannon. The pair was married until 2016, and share two kids: twins Moroccan and Monroe, 9.
