Hugh Hefner Engaged to Crystal Harris, Again: Playboy Founder and Playmate Model set to Marry on New Year's Eve

Playboy founder and mogul Hugh Hefner is set to marry glamour model and Playmate Bunny Crystal Harris... again! Reports confirm that the infamous 86-year-old playboy is engaged to his 26-year-old bombshell girlfriend for the second time... and this time the unconventional couple plans on tying the knot on New Year's Eve... with an intimate wedding ceremony to ring in 2013 in luxurious matrimonial style!

TMZ reported on Saturday, Dec. 1 that Hefner is set to finally walk down the aisle at the Playboy Mansion on the evening of December 31, 2012 - with the same blonde beauty who left him high and dry back in June 2011. That's right, Harris walked out on Hefner just five days before their wedding (June 14). Hefner began dating Harris back in January 2009 and she soon became his "number one girlfriend" alongside Kristina and Karissa Shannon (following his longtime relationship with former Playboy model and reality star, Holly Madison). In anticipation of their summer wedding, (which was set to be filmed for a "Lifetime" special), the July 2011 issue of Playboy featured an exclusive Harris cover and photo spread entitled "Introducing America's Princess, Mrs. Crystal Hefner". The issue hit stands just days before the duo's set wedding date. Later issues featured a sticker covering Harris' "Mrs. Crystal Hefner" title that read "Runaway Bride." Apparently, Harris just wasn't ready.

Reports confirmed that Hefner and his Playmate of December 2009 lover had romantically reunited (which was later confirmed on Harris' Twitter). Now the two officially plan on tying the knot... for real this time.

Apparently since Hefner moved back into the Playboy Mansion earlier this year he has patched things up with Harris, and the couple is better and happier than ever. They have worked out their previous problems, and inside sources claim that Harris feels her time spent apart from Hef really taught her how to be independent and stand on her own two feet (something she felt she needed before becoming a wife). Sources say that the New Year's Eve ceremony will be an intimate gathering with just close friends and family (which will still most likely be carried out in true "Playboy" style).

In the meantime, the couple has been tweeting about the opening of Harris' new L.A. lingerie store, Femme Fatal. They have also shared Twitpics of the Mansion decorated for the holidays:

This will be Hefner's third marriage.
