LOS ANGELES (AP) - Hugh Hefner has married his runaway bride. Hefner and Crystal Harris tied the knot at the Playboy mansion on New Year's Eve, a year and a-half after she broke off their engagement a few days before the wedding. She's 26, he's 60 years older. But Harris said on E!'s "The Girls Next Door" that she never noticed the age difference. After the private ceremony, Hefner and Harris celebrated with Gene Simmons of KISS, Jon Lovitz and other stars. It's Hefner's third marriage, her first. Harris has already changed her name to Crystal Hefner on her Twitter page. She's posted photos of her in her wedding dress and the flowers decorating the wedding room in the mansion.
