Chris Carmack is a married man! The Grey’s Anatomy actor and Nashville and The O.C. alum revealed on Instagram over the weekend that he tied the knot with fiancée Erin Slaver.

Both Carmack and Slaver shared photos from the nuptials, with Carmack’s set against a scenic lake, and Slaver’s set in a dreamy rustic-looking location.

Carmack’s Nashville costar (and upcoming Hallmark Countdown to Christmas star) Sam Palladio also posted a few photos from the big day. “Two of my favorite people in the world got married this weekend and it was the most best weekend ever,” he wrote on a slideshow of pics. “Love you @realcarmack and @erinslaver.”

Palladio appears to have been a groomsman at the ceremony, as he was decked out in a tux that matched the groom’s. The two actors starred as musicians and close friends Gunnar Scott (Palladio) and Will Lexington (Carmack) for all six seasons of Nashville, which concluded in July 2018.

Carmack met his future wife on the set of Nashville as well — Slaver starred as a backup singer for Juliette Barnes (Hayden Panettiere) on seasons 1 and 2. The couple got engaged in March 2016, as revealed by Slaver in an Instagram post featuring “sparkling drinks and fingers” as she and Carmack celebrated with champagne.

In August 2016, the couple welcomed a baby girl. “In my life, I never imagined I’d experience something so beautiful,” Slaver shared on Instagram at the time. ” I couldn’t have made it through naturally without @britteanderson and @realcarmackby my side.”

Congrats to the happy couple!
