“Crystal & I married on New Year’s Eve in the Mansion with Keith as my Best Man. Love that girl!” Hugh Hefner tweeted.
Also delighted, Hefner’s wife kept fans updated throughout the ceremony and after party with posts on Twitter.
“Today is the day I become Mrs. Hugh Hefner. Feeling very happy, lucky, and blessed,” she tweeted.
She has also posted pictures from the event, with her mother, her wedding dress and party decor.
“Happy New Year from Mr. and Mrs. Hugh Hefner,” the groom also tweeted.
Hefner and Harris had planned to marry in June last year, but she called it off.
The couple announced their reconciliation in June.
“Yes I am his #1 girl again. Yes we are happy. Hope that clears up any confusion! Xo,” Harris tweeted.
“I’ve given Crystal Harris a ring. I love the girl,” Hefner also tweeted.
This is the third marriage for Hugh and the first for Crystal.
