Seattle Grace is paging Constance Zimmer.

The Entourage and Boston Legal actress has signed on for a multi-epsiode arc this season on ABC’s Grey’s Anatomy.

Zimmer is playing Dr. Cahill, described as a “confident, self-possessed, laser-focused professional with a wicked sense of humor.” That’s all we know right now about the role, which will run about four episodes later this season.

Shonda Rhimes’ long-running soap is set to say goodbye to its spin-off Private Practice, which is wrapping up its final season by the end of the year. The writer-producer’s new political drama Scandal, however, was recently granted a full season order for its second round on the air.
