Mariah Carey's relationship with her billionaire boyfriend, James Packer, seems to be getting more and more serious.

According to a report, the pop diva has allegedly moved to her billionaire boyfriend's house in Beverly Hills.

"Just five months after they started dating, pop princess Mariah allegedly got her staff to pack up clothes, bedding and furniture to move into his place," Daily Mail reported.

"Luckily for them, it's just five minutes up the road from the home she's been renting for herself and her four-year-old twins Monroe and Moroccan, from her marriage to ex-husband Nick Cannon."

Now that they're living together, are Mariah Carey and her billionaire boyfriend planning to start a family?

Though it may not be clear at the moment, people close to the singer's circle are allegedly noticing how serious the couple is in their relationship.

A source previously dished that Mariah Carey's boyfriend is purportedly very generous not only to the singer, but also to the her soon-to-be ex-husband, Nick Canon.

Reports claimed that Mariah Carey purportedly offered to buy Nick Canon a home in Australia this 2015.

"James has gone through divorce and knows how hard it can be especially when kids are involved. He's maintained a good relationship with his exes and he thinks she should do the same," an insider revealed to Dish Nation.

It has been previously rumored a few months ago that Mariah Carey and her billionaire boyfriend are expecting a baby.

"If Mariah Carey is indeed pregnant with baby number three at the age of 45 years old, it will be interesting to see how the newborn will affect her divorce, career, and alleged mental health issues," Celeb Dirty Laundry said during that time.

"Between Mariah and James - they already have a total of five kids from previous relationships."
