They may have started dating in June, but it looks like things are getting serious between Mariah Carey and Australian businessman James Packer.

According to sources, the 45-year-old pop princess has moved into James' home in Beverly Hills, California.

Mariah apparently got her staff to pack up clothes, bedding and furniture to move into his place, which is just five minutes up the road from the home she had been renting for herself and her four-year-old twins Monroe and Moroccan, from her marriage with rapper-actor Nick Cannon.

Sources told a website that the pair discussed marriage just weeks after they began dating.

The spokesperson for the All I Want For Christmas hit-maker, however, declined to comment on her big move.
