Grey’s Anatomy and Knocked Up actress Katherine Heigl wed singer Josh Kelley in a pre-Christmas wedding ceremony this past weekend in Park City, Utah.

The private reception was witnessed by Grey’s Anatomy costars T.R. Knight – who told PEOPLE it was “incredible and beautiful” – and Sandra Oh, as well as Private Practice star Kate Walsh and new husband Alex Young.

Taking place in a small, private tent at the Stein Eriksen Lodge, the nuptials lasted about 30 minutes in an area decked out in white flowers and white candles. A walkway from the tent to the nearby reception was lined with white candles, illuminating the fresh snow.

Congrats to Katherine and Josh on their “crapshoot”

“It’s a crapshoot. The odds are really bad, especially in this town,” the actress says. “But I have a lot of faith in Josh, and I wanted to have that one day when I stand in front of my friends and my family and honor him and how important he is in my life.”

Gotta make you feel good Josh!
