Mariah Carey claims reason for her breakup with billionaire businessman James Packer is his ties to Scientology.

US Weekly reports Packer’s business manager, Tommy Davis, formerly served as a spokesperson for the Church of Scientology, and sources say he was the one to cause their breakup.

According to sources close to Carey, Davis has also urged Packer to begin a 'Purification Rundown', a Scientology detox program.

We also learnt Packer practised Scientology from 2002 until 2006, but when Carey arrived on his yacht in mid-September, she sensed that he was somehow altered, and suspected Scientology as the cause.

Soon after, she was forced by his staff to vacate the premises.

However, Packer denied Carey's allegations. Report has it that the billionaire businessman severed his tie with Carey because she is “a diva.”

Carey is however demanding a $50 million settlement for “emotional distress.”

Recall that James Parker proposed to Carey with a 35-karat diamond ring earlier this year less than a year after the couple met at a movie premiere in Aspen.
