Kate Walsh's Grey's Anatomy Spin-Off Will Attract Millions

Dr. Addison Montgomery-Shepherd Gets Her Own Show..

There's something special about Kate Walsh.

Special enough to spin Kate Walsh off from Grey's Anatomy into her own pilot and series.

Fans of Grey's Anatomy already know the 39-year-old, 5'10" blue-eyed Californian who dyes her blonde hair red.

Kate Walsh strolled onto the Grey's Anatomy scene decked out in an all-designer black suit and introduced herself to Ellen Pompeo's character by saying:

"You must be the woman who's sleeping with my husband."

But since then the once "adulterous spawn of Satan" has beguiled viewers.

Emerging as Patrick Dempsey's cheating wife who left Manhattan and relocated to Seattle to try and reclaim her marriage, Kate Walsh's character was initially vilified.

Grafting into Grey's Anatomy
Folks eventually softened on Kate's Dr. Addison Montgomery-Shepherd, as the beauty ditched salmon scrubs in favor of a dark blue uniform that signaled Walsh's placement as a permanent part of the medical drama.

Fans also fell in love with Kate's goofy real-life persona displayed in interviews.

"I must say the scenes with Dempsey out in the trailer were pretty fun," Walsh joked honestly about her love scenes set in the Washington wilderness with Patrick.

Med-heads warmed to "the most hated woman on TV" when writers gleaned a sympathetic storyline for Kate -- displaying Addison's loneliness and hurt as the wife of a workaholic surgeon.

Is Kate Walsh married?

Is Kate Walsh looking for a new love?
Those are the main question fans were asking lately, hot on the trails of Kate Walsh's on-screen burgeoning hook up with hot intern Alex Karev, played by Justin Chambers.

Inquiring minds also want to know if Kate is married. According to Parade, she is single.

But today, news of a Kate Walsh spin-off from Grey's Anatomy have message boards a-flying, hot with debate over whether Kate Walsh is leaving Grey's or not.

Astute observers noticed that news reports list her character's full name, Dr. Addison Montgomery-Shepherd, in spin-off reports, leaving the door open to an easy transition back into the Grey's fold if the spin-off -- reportedly to air in May -- dies.
