KATHERINE HEIGL walked down the aisle on Sunday, December 23 2007, to a song written especially for her by her now-husband, musician JOSH KELLEY. The song, performed by acoustic cello and guitar, was named, “December 23,” after their wedding date.

The “Grey’s Anatomy” star selected a traditional, off-the-shoulder OSCAR DE LA RENTA gown for the big day, which OK! magazine Editor RUTH HILTON described as “classic with a modern flare.”
