Haji 'Abdul 'Azim, Prince of Brunei
For his 30th birthday, Prince Azim of Brunei pulled out all the stops and invited A-listers like Pamela Anderson and Marisa Tomei to a enormous celebration at the Dorchester Hotel in London.
But lavish parties have always been his thing. In 2009, the billionaire playboy reportedly threw the "Party of the Year," spending over 70,000 euros on the flowers alone.
Guests can always count on leaving the Prince's celebrations with some pretty stellar party favors, including iPods, diamond jewelry, and luxury Crème de la Mer face creams.
And if you're a real bestie, he may just spoil you rotten. Mail Online reports that the Brunei Prince gifted $6 million worth of jewels to long-time friend Mariah Carey in 1996.
