Seattle Grace is getting some new blood.
Entourage's Constance Zimmer has booked a recurring role on Grey's Anatomy's ninth season, The Hollywood Reporter has learned.
Zimmer will play Dr. Cahill, a confident, self-possessed and laser-focused professional with a wicked sense of humor and appear in at least four episodes of ABC's Shonda Rhimes drama.
She's scheduled to make her Grey's debut in episode 12, tentatively slated to air in late January.
The actress, who most recently guest starred on NBC's freshman comedy The New Normal, has a major role in David Fincher's upcoming Netflix drama House of Cards. She's with UTA and Sweeney Entertainment.
Zimmer becomes the most recent Grey's addition, joining Neve Campbell as Derek's sister, A Different World's Dominic Hoffman -- who made his debut Thursday as Dr. Jeff Russell -- and interns played by Gaius Charles and Camilla Luddington, among others.
