According to The Hollywood Reporter, Christina Ricci has been tapped to guest star on the special episode of ABC's sophomore hit Grey's Anatomy that is slated to air February 5 after the network's broadcast of Super Bowl XL.

The plot for the episode of the medical drama, from creator/executive producer Shonda Rhimes and Touchstone Television, is being kept under wraps. Ricci's character is said to be coming to Seattle Grace Hospital "not as a patient but in a life-and-death situation."
