New details surrounding the very expensive split between Mariah Carey and her former fiancé, James Packer, have emerged. A source tells ET that the Australian businessman was so eager to wed the GRAMMY winner by March that he was willing to do almost anything.

Prior to their breakup, the former couple had been discussing a prenup, according to sources, but nothing was ever signed.

"He felt that ultimately he didn't need a prenup. He was going to marry her without a prenup," a source tells ET. "He loved her so much and wanted to make her happy." 

As for the amount the couple were negotiating as part of the proposed prenup, one source tells ET it was for $50 million while another source says, "that figure never existed."

The abandoned prenup is now a point of contention. Carey feels she is owed the $50 million she believes  was discussed in negotiations, despite never actually tying the knot, the source tells ET “she wants an 'inconvenience fee.’”

“He moved her across the country and relocated her and her kids. He made promises to her that weren't fulfilled," the source said, adding that Carey expects to keep her $10 million engagement ring and wants Packer to buy her a Calabasas home in addition to giving her cash.

Another source counters this, telling ET that "this whole $50 million thing and other noise is a distraction to try and rationalize what she is asking for" in terms of asking for an "inconvenience fee."

The now-exes were keen to keep their Bora Bora wedding date in March 2016. Even if there were to be a ceremony, there was a possibility that the marriage wouldn't be legal. At the time, Carey had yet to finalize her divorce from Nick Cannon, but that didn’t halt the pricey wedding plans.

Carey and Packer had already had scenic villas booked, which ranged in cost from $2,000 to $15,000 per night.

"Mariah had a wedding dress at that point from Valentino couture and she had a mini version made for Monroe," the source said. "Mariah is festive and wanted multiple weddings. She was planning multiple weddings and multiple ceremonies with James."

The source confirms that the “Against All Odds” singer had also abstained from having sex with her fiancé before saying, “I do.”

“Mariah wanted to wait until she was married,” the source tells ET.

On a more personal level, the singer feels she’s owed an apology.

"Mariah would like James to apologize for breaking up with her so publicly" the source said. "She feels like he used her to increase his profile in America and globally to help further his business interests.”

Despite the split, the source adds that Carey is “recovering well.”

ET has reached out to a publicist for Packer for comment.
