Hotel heiress and notorious party girl Paris Hilton, 25, and her sister Nicky, 23, are expected to inherit over $50 million worth of her great-grandfather's Hilton hotel chain. Hilton, who is often seen with her pet Chihuahua, Tinkerbell, won Playboy Magazine's "Sex Star of the Year" in 2005 and cameos in Hollywood films. But Hilton's life has also been rich with scandal.
