The 86-year-old Playboy boss wed former bunny Crystal Harris, 26, on Monday, with brother Keith as his best man.
The couple exchanged vows beneath a rose arc adorning the staircase at the Playboy Mansion in Holmby Hills, Los Angeles.
Harris, who broke off the couple's engagement, just before a planned 2011 wedding - and then auctioned off her ring, wore a strapless pink rosette ""mermaid"" gown, while the groom donned a tux for his third trip down the aisle.
Hef confirmed the wedding had taken place in a tweet on New Year's Day, writing, ""Crystal & I married on New Year's Eve in the Mansion with Keith as my Best Man. Love that girl!""
He also included a photo of the newlyweds.
