Grey's Anatomy enlists 'Entourage' actress, Constance Zimmer, for a recurring role -- TV Guide learned exclusively.
The Entourage and Boston Legal alum will play Dr. Cahill, a confident, self-possessed and laser-focused doc with a wicked sense of humor. Details of her specialty are being kept under wraps, but we'd like to think she could be another surgical fellow who keeps the attendings on their toes.
Another episode of Grey's Anatomy airs on Thursday on ABC.
