Mariah Carey has moved into her new beau's Beverly Hills mansion

Los Angeles - Mariah Carey has moved into James Packer's house.

The Hero hitmaker, 43, has reportedly boxed up her belongings and is now living with her billionaire boyfriend, 48, in his Beverly Hills mansion in California, just five months after they started dating, according to gossip site TMZ.com.

The blonde beauty's big move came just a week after she threw a Halloween bash for her four-year-old twins Moroccan and Monroe, with her estranged husband Nick Cannon, 35, and her new beau both in attendance.

But, despite her current lover and former flame in the same facility, there was no bad blood between the pair and she said "it was cool. It was nice. It was really good for the kids."

Mariah split from Nick, the father of her twins, last summer after six years of marriage and has wasted no time throwing herself into her new romance as it is believed she and James are eager to tie the knot in the near future.

A source said previously: "James wants to marry her sooner rather than later, and she is very open to the idea."

And it seems their romance is travelling fast as the couple are said to have already discussed having a child together.

The insider explained: "Mariah feels that having a child with James would be a blessing from God. She wants another child and is telling friends she's not too old."

Meanwhile, James - who has been married twice before - already has three children from previous relationships.
