Park City, Utah (CNS) - Dr. Izzie has just gotten married. Grey's Anatomy's Katherine Heigl has wed singer boyfriend Josh Kelly Sunday.

The affair took place in a private tent at the Stein Eriksen Lodge and lasted about 30 minutes. Co-stars T.R. Knight, Sandra Oh, and Kate Walsh attended the reception.

Officiated by Unitarian minister Tom Goldsmith, the 29-year-old Emmy award-winning actress walked down the aisle to a song written by Kelley. The couple wrote their own vows.

Sources say that the bride enjoyed a "really feminine and small" bridal shower.

The actress told Vanity Fair that she had no doubts about marriage. "It's a crapshoot. The odds are really bad, especially in this town. 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."

Heigl met her future husband in 2005 when she appeared in the video for his song "Only You." They became engaged in 2006 and set the date in June 2007.
