But, ahead of couple's tying of the knot set for New Year's Eve, the Playboy Playmate celebrated her upcoming nuptials with a bridal shower.
The affair, hosted by Harris' friend Ashley Matthau and Hefner's sister-in-law Caya Hefner, was held at Matthau and Harris' lingerie store/party venue Femme Fatale in Studio City, Calif., Wednesday.
"I had the cutest, sweetest, and most fun night with my friends and family," Harris tweeted following the shower. "So special. Happy girl."
The Playboy founder and his once-again fiancée obtained a marriage license Dec. 4, announcing their wedding news to a class at the University of Southern California that same day.
"Today is a special day for us, because after class we are going to the courthouse to get our marriage license," Hefner told the students.
And just in case their New Year's Eve wedding doesn't go off without a hitch, Hefner and Harris have 90 days from the time they nabbed their license to say "I do."
