While Nick Cannon may have been able to arrange a private day or two at Disney for his soon-to-be ex-wife, Mariah Carey's new billionaire boyfriend is supposedly able to buy her out of her Las Vegas contract, if he likes. According to the latest gossip news updates, James Packer is so determined to keep the "Butterfly" beauty by his side that -- thanks to his $4-plus billion net worth -- he is offering to buy all the tickets for her Infinity Tour residency so his new girlfriend can spend the rest of the year and then some vacationing around the world in the absolute lap of luxury. Not one to be completely overshadowed, the America's Got Talent host recently posted a picture to Instagram reminding everyone that he once dated Kim Kardashian in her prime -- and no foreign billionaire is ever going to be able to take that from him.
