Mendel. Hilton completed her look with simple pearl earrings, pointed pumps and a camel coat. Hilton and Rothschild married in July at London’s Kensington Palace, and soon afterward, Hilton stirred headlines when she considered (and ultimately took) her husband's last name. "You know, I'm very traditional, and that's just what happens," said Hilton in an exclusive with Fox News Magazine last year. "The bride takes her husband's last name."
