After just one month of dating, and three months of being engaged, Kate Walsh and Alex Young are officially husband and wife.
The wedding took place Saturday at the Ojai Presbyterian Church in Ojai, Calif., with a reception at the Ojai Valley Inn & Spa.
Some of Kate Walsh's Grey's Anatomy co-stars, such as Katherine Heigl and fiance Josh Kelley, T.R. Knight, Chandra Wilson, James Pickens Jr., Justin Chambers and wife Keisha, along with Shonda Rhimes, were in attendance.
Also attending were actress Kate Beckinsale and her director husband, Len Wiseman. Reports indicate that approximately 110 guests were on hand.
A lavish reception was scheduled to follow at the Ojai Valley Inn & Spa's Casa Elar, a Spanish-style estate where guests enjoyed sit-down dinners.
Kate Walsh, 39, will play her Grey's Anatomy character, Addison Montgomery, on a spin-off debuting on ABC on September 26, Private Practice.
Just last week, the TV star told Entertainment Tonight that with her career and her engagement to Alex Young, "I'm living a very good dream."
Young, 35, is a production executive at Fox. His proposal to Kate in May was discovered after she was spotted her wearing an engagement ring.
