Kate Walsh plays Rebecca Wright in the NBC comedy series "Bad Judge."

Walsh is widely known for her starring role as Dr. Addison Montgomery on "Private Practice," a spin-off of the hit show "Grey's Anatomy." The enormous success of her character on "Grey's" led writer and creator Shonda Rhimes to create a spin-off based solely on Walsh's character. 

During her two seasons on "Grey's Anatomy," the show received a SAG Award for best ensemble in 2007. "Grey's" won the Golden Globe for best television drama series in 2007 and the show also received Emmy nominations for outstanding drama series in 2006-07.

Most recently, Walsh co-starred in the TV adaptation of "Fargo," alongside Billy Bob Thornton and Martin Freeman. Her previous small-screen credits include "CSI," "Karen Sisco," "The Mike O'Malley Show," "Mind of a Married Man" and "The Drew Carey Show."

On the film side, Walsh appeared in the Courteney Cox-directed film "Just Before I Go" that recently unspooled at the Tribeca Film Festival. She also recently finished production on two other indie pics - "Staten Island Summer," produced by Lorne Michaels, and "Dermaphoria."

In 2012, Walsh was seen in Summit Entertainment's "The Perks of Being a Wallflower," opposite Paul Rudd, Emma Watson and Logan Lerman. Also, Walsh was in the supernatural thriller "Legion," starring opposite Paul Bettany and Dennis Quaid, and she made a cameo in "Scary Movie 5," a part of the American comedy franchise. 

In 2005, Walsh co-starred opposite Will Ferrell and Robert Duvall in "Kicking & Screaming." Other film credits include "Under the Tuscan Sun," "After the Sunset" and "The Family Man."

Walsh returned to her theater roots in 2010 and appeared in an off-Broadway production of "Dusk Rings a Bell."

Walsh began her acting career in Chicago, where she studied at the renowned Piven Theater Workshop. Walsh then starred in multiple theater productions at the Shakespeare Repertory, including "Born Guilty," "Moon Under Miami" and "Troilus and Cressida." 

Outside of the entertainment business, Walsh launched her own self-financed beauty company and fragrance, Boyfriend, in 2010. In a partnered launch with the Home Shopping Network, Boyfriend sold out in a record-breaking 30 minutes, and in 2011, it climbed the ranks to become a top-10 seller. Her second fragrance, Billionaire, debuted a year later. 

Walsh currently resides in Los Angeles.
