Wittrock, who also appeared in the Primetime Emmy-winning TV movie "The Normal Heart," sported a dark suit during the special occasion while his bride wore a simple long-sleeved wedding dress.

The Lenox, Massachusetts-born thespian also tweeted a snap of him and Roberts posing with their bridesmaids and groomsmen. In the photograph, the new husband and wife stand on a patio outside with their friends lined up on both side of them.

One of the wedding attendees also shared a lovely photo of the newlyweds at the reception getting ready to cut their two-tiered wedding cake. "Congratulations to the wonderful and happy newly weds! #sarahfinnhitched @sarahroberts26 @wittyrock1," their friend wrote on Instagram.  

Both Wittrock and Roberts are graduates of Juilliard, a performing arts conservatory established in 1905, and considered as one of the world's leading music schools with some of the most prestigious arts programs, Broadway.com reported.

Meanwhile, Wittrock recently talked about his character Dandy on the fourth installment of the hit FX anthology series.

In an interview with TVLine, Wittrock called Dandy "a kid who never grew up... a kid who's incredibly wealthy but emotionally stunted at a certain age."

"We'll learn that there was some trauma in his youth - and also that there might be a bit of incest happening," he added. "We'll also learn that maybe, more broadly to say, psychosis runs in the family."

When asked to describe the dynamic between Dandy and his mother, Gloria, (Frances Conroy), Wittrock said, "It changes every episode, but he's still very, very dependent on her, yet he's trying to claim his independence, as you kind of do in your adolescence. Except his form of finding himself goes in a very dark direction."

"Part of the message of the show is that Dandy is the biggest freak, although he looks the most normal," he added.
