Addison's coming back.
Actress Kate Walsh will be bringing her character, Addison Montgomery, back to Seattle Grace Hospital and Grey's Anatomy on March 31.
Spoiler alert: According to TV Line, Addison, who is currently a character on Grey's spin-off, "Private Practice," will return to help with a medical crisis involving a baby. With Callie Torres (Sara Ramirez) currently pregnant on the show, this could be the tie-in. Incidentally, this will also be the much-touted musical episode.
