"Today is the day I become Mrs. Hugh Hefner. Feeling very happy, lucky, and blessed," Femme Fatale lingerie shop owner Harris tweeted before saying "I do" in front of family and close friends in an evening ceremony.
For her big day, Harris donned a floor-length mermaid-style soft pink strapless gown, while Hefner suited up in a black tuxedo. Hefner was equally as excited as his bride to swap vows on New Year's Eve. "Crystal & I married on New Year's Eve in the Mansion with [brother] Keith as my Best Man. Love that girl!" he tweeted after they were declared husband and wife underneath an archway of pink, red and white flowers.
After the newlyweds said their vows, they joined revelers -- including Rascal Flatts' Joe Don Rooney, Gene Simmons and Jon Lovitz -- at a joint wedding reception/New Year's Eve party, done in an Art Deco theme. Jazz singer Brenna Whitaker and her band performed at the bash.
Despite the couple's rocky romance -- Harris was dubbed "runaway bride" when calling off her June 2011 wedding to Hefner days before the ceremony -- the bride tells Us Weekly her union with Hef has staying power.
"When the wedding didn't work out the first time, it was because of me. I needed to explore out there and take the time away [from Hef and the Mansion]. The time away really helped make me realize that where I'm meant to be is here with Hef," Harris says. "Our relationship is better than it ever has been before. I'm very happy and Hef's very happy and we're excited."
