Kathleen Erin "Kate" Walsh (born October 13, 1967) is an American film and television actress, currently known for her role as Dr. Addison Montgomery on the ABC dramas Grey's Anatomy and Private Practice.
In 1960s Baltimore, dance-loving teen Tracy Turnblad auditions for a spot on "The Corny Collins Show" and wins. She becomes an overnight celebrity, a trendsetter in dance, fun and fashion. Perhaps her new status as a teen sensation is enough to topple Corny's reigning dance queen and bring racial integration to the show.
