It’s a fairy tale come true for Claire Coffee!

Grimm‘s alluring villainess wed her Prince Charming – musician Chris Thile of the Punch Brothers – Dec. 23 in an intimate Smoky Mountain wedding, PEOPLE confirms.

The duo tied the knot at Blackberry Farm, a rustic luxury resort in pastoral Tennessee, after two and a half years together.

The couple made it a decidedly small, family-oriented affair.

“[There were] 20 people in attendance TOTAL,” Coffee tells PEOPLE. “Our immediate family and grandparents, plus Chris’s best friend Rob Moose [of Bon Iver], who played Bach on violin for my walk down the aisle.”

Coffee said her sister Abbie officiated the ceremony, which they wrote themselves, aside from the traditional Irish vows they used to swap “I do’s.”

The bride, 33, tells PEOPLE she wore a 76-year-old vintage lace gown, purchased alongside her vintage veil at Xtabay Vintage Bridal Salon in Portland, Ore., where Grimm shoots. The groom, 32, donned a dark brown wool suit custom made by Against Nature in New York City. After the ceremony, the just-married couple and their guests dined in the resort’s award-winning wine cellar.

The hard-working newlyweds don’t have time for honeymoon, Coffee shares, but “we spent Christmas with our families at Blackberry after the wedding.”

It was presumably there that she first discovered one of the fringe benefits of marriage.

“Forcing @christhile to listen to the new Beyoncé album in its entirety because as his wife it is now legal for me to do so,” she Tweeted earlier in the week.
