After just over a month of dating, and just over three months of being engaged, Kate Walsh and Alex Young officially tied the knot over the weekend.

The wedding of Walsh and Young took place Saturday at the Ojai Presbyterian Church in Ojai, Calif., and the reception was at the Ojai Valley Inn & Spa after.

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.

Many of Kate Walsh's Grey's Anatomy co-stars, including Katherine Heigl and fiance Josh Kelley, as well as T.R. Knight, Chandra Wilson, James Pickens Jr., Justin Chambers and his wife Keisha, along with Grey's Anatomy and Private Practice creator Shonda Rhimes, were in attendance.

Kate Walsh is gearing play her Grey's Anatomy character, Addison Montgomery, on a spin-off series entitled Private Practice (as we all know) September 26.

Like most brides, Kate experienced the occasional meltdown as she got ready for the big day - a wedding she planned very quickly, to boot!

Just last week, the busy TV star told Entertainment Tonight that with Private Practice set to get underway soon and her engagement to Alex Young, "I'm living a very good dream."

Young, 35, is a production executive at 20th Century Fox. His proposal to Kate in May was discovered by reporters who spotted her wearing an engagement ring at a television event. The two went public at a Barack Obama fund raiser.
