Nicky Hilton Rothschild & James Rothschild
What could possibly be more self-explanatory than the union of a Hilton and a Rothschild? We're all (perhaps too) familiar with Nicky, but her husband James, British banker and heir to his family's fortune, has always chosen to remain out of the spotlight. Nevertheless, he seems down to accompany his wife to high-profile functions and fundraisers, and, we're sure, ready to write checks for good causes.
