Hugh Hefner Engaged!

The man behind the Playboy empire is engaged once again, he confirmed via Twitter on Monday.

Hugh Hefner proposed on Christmas Eve to his 24-year-old girlfriend Crystal Harris, reports MTV.com. Hugh posted on his web page, "After the movie tonight, Crystal and I exchanged gifts. I gave Crystal a ring. A truly memorable Christmas Eve... When I gave Crystal the ring, she burst into tears. This is the happiest Christmas weekend in memory." This will be the third marriage for the 84-year-old media mogul.

Crystal met Hugh in 2008 at the Playboy Mansion during one of the magazine's notorious Halloween parties. She went on to be named Playboy's December 2009 Playmate. Unafraid of critics, Crystal has even broached the subject of their 60 year age difference. The model has said, "A lot of people talk about the age difference between Hef and I, but I don't see the age difference at all. If anything, I feel like I'm the adult and Hef's the kid." She also insisted that she's not into Hef for his money. "I have my own career going," she says.
