Grey's Anatomy star Kate Walsh officially married

Life doesn't always have to imitate art: Kate Walsh has officially bagged her McDreamy.

The Grey's Anatomy cum Private Practice star has tied the knot with her fiancé of just four months, movie executive Alex Young, in a sunset ceremony at California's Ojai Presbyterian Church in the resort town just north of Los Angeles, People reports.

The 39-year-old bride donned a custom made gown from go-to celeb wedding dresser Monique Lhuillier for her trip down the aisle. The 36-year-old 20th Century Fox exec wore the requisite penguin suit.

The duo swapped vows in front of slightly more than 100 guests, among them Walsh's former Grey's Anatomy costars Sara Ramirez, Katherine Heigl and Chandra Wilson. Show creator Shonda Rhimes was also present for the ceremony, which kicked off with a gospel choir rendition of Rascal Flatts' hit "Bless the Broken Road," as was Kate Beckinsale and her hubby, director Len Wiseman.

According to the magazine, Walsh's big day is already in danger of turning into a big night as well at the nearby Ojai Valley Inn & Spa resort. The nuptial madness is scheduled to continue with a reception and post-wedding sit-down dinner at the inn's Spanish-style estate, Casa Elar. The newlyweds are also expected to host a post-wedding brunch for their guests on Sunday morning.

It's the first marriage for both, and while the fairy tale ending was smoothly executed, the run up to the union wasn't totally bump-free.

"I had a fitting a few days ago and who knew someone could get that hysterical about a bra!" Walsh told Entertainment Tonight last week of her brief flirtation with being a bridezilla. "The sad part was there was a mirror there, so I had to see my face turn to stone, snakes coming out of my hair. It was bad. I can't believe I had a meltdown over a bra!"

Still, the new bride said, "I'm living a very good dream."

Walsh and Young announced their betrothal last May—he popped the question during a trip for two to San Francisco—just one day after ABC announced it had picked up her spinoff for the fall season. Walsh confirmed the engagement after being unable to hide the massive sparkler on her finger, a Neil Lane Jubilee-cut diamond.

The duo were first spotted together this spring and went public at a Apr. 26 Los Angeles fundraiser for Barack Obama. It's unclear how the camera-ready twosome first met, though Young is a close friend of Walsh's boss, ABC president Steve McPherson.

It's also unclear whether the happy couple is planning on honeymooning in the immediate future, though both will need to hightail it back to the daily grind sooner or later. Private Practice, serving with high hopes as ABC's new Wednesday night anchor, premieres Sept. 26. (E! Online)
