Katherine Heigl Ties The Knot!

Grey's Anatomy beauty Katherine Heigl, 29, married musician Josh Kelley, 27, Sunday in a private ceremony in Park City, Utah.

Guests at the black tie nuptials - held at the exclusive Stein Eriksen Lodge - included Katherine's Grey's co-stars T.R. Knight, Sandra Oh and Kate Walsh.

Katherine - who also starred in the summer blockbuster movie Knocked Up - met Kelley in 2005 when she appeared in a video for his song "Only You." Katherine told TV's Extra last week that she's anxious to start a family with Josh.
