Grey's Anatomy's Kate Walsh married movie executive Alex Young on Saturday, PEOPLE confirms.
Walsh, 39, wore a custom-made Monique Lhuillier wedding gown as she and Young, 36, exchanged vows at the Ojai Presbyterian Church in the town of Ojai north of Los Angeles. A gospel choir sang "Bless the Broken Road" by Rascal Flatts at the beginning of the ceremony.
Among the about 100 guests were Grey's costars Katherine Heigl, Chandra Wilson, Sara Ramirez and Justin Chambers, as well as the show's creator Shonda Rhimes. Also attending were actress Kate Beckinsale and her director husband Len Wiseman.
A lavish reception was scheduled to follow at the Ojai Valley Inn & Spa's Casa Elar, a Spanish-style estate where guests enjoyed a sit-down dinner.
Wedding planner Jo Gartin of Love Luck and Angels had decorated the estate with hundreds of candles for an intimate atmosphere.
Walsh met Young, a production co-president at 20th Century Fox, in February and they were engaged three months later.
"I know – I'm literally living the dream," Walsh told PEOPLE at the time. "But you know when you know. I was not expecting it, so it's kind of amazing."
Walsh is now starring in a Grey's spinoff on ABC called Private Practice.
