Hugh Hefner Crystal Harris Engagement Ring Makes TwitPic Debut

The soon-to-be third Mrs. Hugh Hefner is giving us a look at the sparkler she’s been sporting on her left ring finger since receiving a Christmas morning marriage proposal from the men’s mag magnate.

The Playboy boss, 84, presented Playmate Crystal Harris, 24, with a huge diamond ring over the holiday weekend, and the blonde bombshell has promptly taken to Twitter to show the rock off.

“For those of you who have been asking to see my ring here it is… My engagement ring from my love @hughhefner,” an ecstatic Harris wrote beneath an image of the pricey bauble. “The most memorable Christmas ever. I love him,” she later added.

Crystal also Tweeted a picture demonstrating just how she charmed Hefner, her blonde hair thrown back as she struck a sultry pose.

Harris met Hefner at a Halloween party in 2008 and began dating him the previous January. At the time, was also dating identical twins Kristina and Karissa Shannon. Hefner ended his relationship with The Shannon Twins in January and has remained monogamous with Crystal ever since — despite his colorful declarations to former girlfriend Holly Madison about the perils of marriage.

And for a guy who’s love of polyamorous relationships is the subject of a hit reality show (E!’s The Girl’s Next Door), that’s impressive.

Hef was last married to 1989 Playboy Playmate of the Year Kimberly Conrad. The pair separated in the late nineties but only got around to make their split official with a divorce earlier this year.
