Kate Walsh Is Returning To "Grey's Anatomy" Season 18 As Dr. Addison Montgomery

After two seasons of "Grey's Anatomy," Walsh left the show to lead "Private Practice" which was a Grey's spin-off and ran for six seasons.

Fans of Grey's Anatomy have reason to celebrate. Dr. Addison Montgomery is coming back for the upcoming 18th season of the medical drama series. Kate Walsh, who plays Dr. Montgomery has announced on social media that she will be coming back to the show.

“Well, well, well, would you look who it is,” Walsh said on the show’s official social media accounts. “That’s right, my loves, Dr. Addison Montgomery is coming back to Grey Sloan Memorial Hospital and I’m so excited to be home again joining Shonda [Rhimes], Ellen [Pompeo], and the rest of the incredible cast. Just wait until you see what she has in store for you.”



The actress also announced the exciting news through the popular "Questions I Get Asked" trend. To the question, "Will you be returning to Grey's Anatomy" she responds with "yes" and this is followed by Welsh in the doctor's outfit lip-syncing to the iconic Emma Roberts line from American Horror Story saying: “Surprise, b****. I bet you thought you’d seen the last of me.” She then asks fans to stay tuned and wrote in the caption: "It’s really happening. Dr. Addison Montgomery will see you shortly."


Walsh made her first appearance on the show for the finale of season one as Dr. Derek Shepherd's (Patrick Dempsey) estranged wife. After two seasons, she left the show to lead Private Practice which was a Grey's spin-off. “I feel like we wrapped it up,” Walsh had told TV Line in 2017 about the likeliness of her returning to Grey's. “I’m not saying if Shonda was like, ‘We’re gonna do a very special episode of Grey’s where… ‘ But she really consciously, we did it all. We had the spinoff, and we had all that. It was an amazing experience and journey,” she added. But here she is, in the new season set to air on September 30 at 9/8c.



While Walsh worked on Private Practice, which ran for six seasons, she also made guest appearances on Grey's. In total, she has 59 episodes on the show, according to Deadline. In addition to Walsh, fellow actress, Kate Burton is also set to reprise her role as Dr. Ellis Grey in multiple episodes of the new season. This is in line with the surprise comebacks last season of former Grey’s stars Patrick Dempsey, T.R Knight, Chyler Leigh, and Eric Dane. Kim Raver, who portrays the role of Dr. Teddy Altman, also returned to the medical drama as a recurring after being away for several seasons and is now a series regular again.



The show saw several main characters including Giacomo Gianniotti who played Dr. Andrew DeLuca and Jesse Williams who played Dr. Jackson Avery leaving the show in the previous season. But the narrative of Season 17, with Meredith’s scenes mostly taking place on a beach as she battled for her life due to COVID-19, allowed a number of dead characters such as Derek (Patrick Dempsey), her husband; her friend George (T.R. Knight); and her sister Lexie (Chyler Leigh) to be featured on the show, as per Variety. Additionally, Peter Gallagher will be debuting on the show as Dr. Alan Hamilton, a doctor who knew Ellis.



It's not just the fans who are excited about the new season and all there is to come, Pompeo who plays Walsh's onscreen rival, who plays Meredith Grey, is just as excited as well. "Let's give them what they want... quality tv drama," she commented on Instagram. Grey's Anatomy became the longest-running medical drama on American television, surpassing ER, in 2019. "How do you walk away from a hit? The fans will dictate when the show ends," Pompeo had told PEOPLE at the time. "As much as we think we’re in control, we’re not. It’s the fans’ show at this point. They control how long the show goes. We’ll see. I kind of just take it year by year and see."
