It seems like Mariah Carey made a huge upgrade in her life with her new billionaire Australian boo. In fact, her new boyfriend is so obsessed with her that he invited everyone on his yacht just to listen to her music the entire time because he loves her THAT much. James Packer, who according to Forbes is one of the richest men in Australia, threw the ultimate party for Ms. Carey off the coast of Sardinia. Of course, the entertainment consisted of Mariah, Mariah and then some more Mariah. According to sources, he’s been pursuing her for the longest and finally snatched her up. Sources also revealed that they got serious almost immediately and that they’re both looking for something long-term and real. Congrats to these two!
