“GREY’S Anatomy”’s upcoming 18th season has just been event-ized.

TVLine has learned that Kate Walsh is set to reprise her role as Addison Forbes Montgomery in multiple episodes.

Walsh made her memorable “Grey”’s debut in the Season 1 finale as Derek’s surprise wife. Addison would continue to be a major player at the hospital for two more seasons, leaving in 2007 to front the “Grey”’s spinoff “Private Practice,” which ran until 2013.

Back in 2017, Walsh spoke to TVLine about a potential Addison comeback, admitting at the time, “I feel like we wrapped it up.” She then added, It was an amazing experience and journey.”

“Grey’s Anatomy”’s season premiere is set for Sept. 30.
