The former star of Grey's Anatomy, who's been plying her medical profession on this season's new Private Practice (which, due to the writers' strike, is on a break until fall), is set to return to her original series in her role as Dr. Addison Montgomery.
The one-episode guest spot will be seen this spring, ABC confirms to EW.com.
No firm date has been set for when it will air, but the network has five original episodes of Grey's ready for broadcast starting April 24. --Stephen M. SilvermanMichael Desmond/ABC
