Playboy founder and eternal chick magnet Hugh Hefner is ready to tie the knot.

At age 84, Hef is engaged to 24-year-old Playmate Crystal Harris. The two met in 2008, and Hef put her into dating rotation the following year, along with the Shannon twins.

Now that the twins have moved out of the Playboy Mansion, ol' Hef has found love with one blonde, so he wants to make it official.

He popped the question on Christmas Eve. The dude is all romance. Hef is even reportedly doing everything he can to make sure the sparks still fly.
