He's 86 and she is 26...that's only 60 years, right??  Ha!  Hef said "I do" to Crystal Harris on New Years Eve at the Playboy Manion.

"Happy New Year from Mr. and Mrs. Hugh Hefner!" Hefner tweeted early on yesterday.

"Crystal & I married on New Year's Eve in the Mansion with Keith as my Best Man. Love that girl!" Hefner also wrote on Twitter.

The couple tied the knot more than a year after their planned 2011 wedding was cancelled when Harris got cold feet.

The blonde Playboy Playmate of the Month for December 2009 ditched the adult entertainment mogul in what was called a "change of heart" five days before a lavish June 2011 wedding before 300 guests.

Harris, who appeared on the July 2011 cover of the adult magazine with a "runaway bride" sticker covering her bottom half, tweeted on Monday that she was ready to commit and changed her name to "Crystal Hefner" on the micro-blogging site.

"Today is the day I become Mrs Hugh Hefner," Harris, who has a psychology degree, wrote on Twitter after writing "Feeling very happy, lucky, and blessed."

Happy New Year!!!

Xoxo
