The 86-year-old Playboy magazine founder married 26 year-old Crystal Harris, at a private Playboy Mansion ceremony on New Year’s Eve.

Harris broke off a previous engagement to Hefner just five days before they were to be married in 2011. Things got a tad nasty then with her making rude comments about his ability in bed and him telling the world he was heart broken.

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."

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

Hefner also tweeted about the nuptials.

"Crystal & I married on New Year's Eve in the Mansion with Keith as my Best Man. Love that girl!" he wrote, referring to his brother Keith Hefner.

A Playboy spokesperson confirmed that the couple celebrated at a New Year’s Eve party at the mansion with guests that included Gene Simmons of KISS.

Hefner has been married twice before in 1959 and 1989. He and his second wife Kimberley Conrad, also a former Playmate, divorced in 2010 after a lengthy separation. His first marriage to Mildred Williams ended in divorce in 1959. He has two children from each marriage.
