Surprise! Chicago Med star Nick Gehlfuss reveals to PEOPLE he recently tied the knot.

At Monday's PEOPLE & Entertainment Weekly's Upfronts Party in New York City, the actor shared that he married girlfriend Lilian Matsuda in a "big wedding in Ohio" and has been spending part of his honeymoon promoting the NBC franchise of Chicago-set procedural dramas.

"I wanted to invite a lot of my cast mates, but, because we're a franchise, I would have had to invite the entire Chicago franchise. I started on P.D. and I went to Fire, and now with Justice, it would have been crazy," Gehlfuss said. "It rained that day in the morning, which is good luck. And then it was perfect after that. And it was on Friday the 13th, and the next day it dropped twenty degrees and then Sunday, blizzard, snowing on the way here."

As for the couple's honeymoon, the star reveals they plan on going abroad. "Besides the one we're having right now, we're going to go to Japan probably at some point," shared Gehlfuss, who gave his bride pearl earrings for their big day.

Also at the PEOPLE & Entertainment Weekly's Upfronts Party was Gehlfuss' costar Yaya DaCosta. "We're so happy for Nick. We're ecstatic. She's unbelievably cool They're perfect," the actress gushed about the newlyweds.

Laverne Cox, Vanessa Hudgens, America Ferrara, Jaimie Alexander, Christian Slater, Ray Liotta and Mandy Moore all gathered to celebrate the best of the upcoming TV season.
