OK! Exclusive: Katherine Heigl Married!

In a ceremony described by guests as a "winter wonderland," Grey's Anatomy star Katherine Heigl and her musician beau Josh Kelley were wed Sunday afternoon in an intimate, fairy-tale ceremony in Deer Valley, Utah.  And OK! was there to bring you the exclusive details!

With tears filling the eyes of the 80 friends and family in attendance, the 29-year-old beauty looked exquisite in her traditional, white Oscar De La Renta gown, as she made her way down the aisle to a song written specifically for the ceremony by her waiting groom.

Wanting to keep things simple and elegant, the bride and groom eschewed readings and went straight to exchanging their vows and rings, which Katherine had custom designed for the blessed event.

Supporting Katherine on her most important day was her sister and maid of honor Meg and her three bridesmaids, dressed in cranberry red cocktail dresses, also by Oscar De La Renta.

Josh, who met his bride when she starred in the video for his 2005 single "Only You" was joined by four groomsmen, including Katherine's Grey's co-star T.R. Knight, and Josh's younger brother Charles as best man, all dressed head-to-toe in Tommy Hilfiger.

T.R. wasn't the only Grey's cast member there to cheer Katherine on. Also joining their Emmy-winning co-star were Sandra Oh, Kate Walsh (whose wedding was also featured exclusively in OK!) and Justin Chambers.

Guests at the wedding were given gift baskets of Christmas cookies as they arrived at the ceremony, and then later they dined on traditional Christmas fare at the reception.

On Saturday, Katherine and her gal pals celebrated her last day of single-hood with an all-day trip to the spa, complete with buckets of champagne from Moet & Chandon.
