People.comis reporting that 84 year old Hugh Hefner has popped the question to his 24 year old girlfriend Crystal Harris.

Hefner tweeted that "after a night out at a movie he gave Harris a ring and a truly memorable Christmas eve." Crystal reportedly burst into tears and said that "this was the happiest Christmas weekend in memory".
