Prince William stands to inherit the British throne someday, but for now, he'll have to make do with the nearly $16 million or so that he inherits today. This is the prince's 30th birthday and he can now get his hands on half of Princess Diana's estate, reports the Telegraph. The prince, who already has a few million of his own, is believed to be planning to sign up for another tour as a Royal Air Force search-and-rescue pilot, and officials say he's not planning to spend his new millions on a big country house in the near future. "Whatever the financial position might be, you will see no obvious change of lifestyle over the coming weeks or months," notes a royal aide. Click to find out Wills' current salary.
