Showing quite a bit of class, Hugh Hefner refused to take back the engagement ring he gave ex-fiancé Crystal Harris. Last week, the 'Playboy' centerfold broke up with him just five days before their wedding. reports that Harris returned to the Playboy Mansion on Sunday night to return the ring but the 'Playboy' founder told her to keep the 3-carat, $90,000 ring. And if that wasn't enough, Hefner also let his runaway bride keep the Bentley he'd given her. He did take back their King Charles dog, Charlie.
