The couple got engaged in June 2006, after they first met on the set of his music video 'Only You' in which she starred.
He wrote the song 'Hey Katie' for her not long after.
They decided not to live together until after the ceremony, to leave something new and exciting until after the marriage. "I think I just wanted to save something for the actual marriage... I wanted there to be something to make the actual marriage different than the dating or the courtship." (Wikipedia)
Heigl and Kelley married in Stein Erissen Lodge in Park City Utah on the 23 rd December 2007.
All of her co-stars in Greys' Anatomy, TR Knight (groomsman), Sandra Oh, Ellen Pompeo, Kate Walsh and Justin Chambers were in attendance. Heigl walked down the aisle to a song that had been specifically written by Kelley and was performed by cello and guitarists. They both wrote their own wedding vows.
Only two years later the couple announced on the 9 th September 2009 that they were adopting a baby from South Korea.
Later in September they adopted Nancy Leigh (named after Heigl's mother and sister), who has the nickname of Naleigh.
The couple adopted another baby, Adelaide Marie Hope in April 2012 from the US.
Happy Wedding Anniversary Katherine and Josh!
