The two told the outlet in August that a fews days before rehearsals began, Murin hosted a party and, as she said, “got a little bit drunk.”

“She may have kissed me in the hallway,” Donnell said.

“We were literally starting rehearsals two days later, and I was like, ‘What did I just do? I do not want a boyfriend right now,’ and I’d known him for so long,” Murin said. “Everyone was always like, ‘Colin is so good looking, he’s so hot’…And I was like, ‘Really? I just don’t see it.’ And then when I went back into my apartment that night my best friend was still there and I was like, ‘I see it now. I get it.'”

“We kept [the relationship] quiet for awhile; up until we started actual performances,” Murin said. “It was like one of those surprise things — and now we live together and have a dog.”
