84-year-old Hugh Hefner is getting married to 24-year-old girlfriend Crystal Harris and, according to the old man's Twitter account: "This is the happiest Christmas weekend in memory." So that basically means it's the happiest Christmas since last Christmas, right?

The couple were engaged on Friday. This will be Hefner's third marriage, which is actually a little bit surprising, no? The far younger Harris was December 2009's Playboy Playmate of the Month, which is nice and everything, but now she gets the ageless Hef all to herself. Well, not really, but you know what we're saying.

Congrats, you crazy kids!
