A representative for ABC confirmed to USA TODAY Thursday that Walsh will return to the long-running hospital drama for its upcoming 18th season.
Walsh, who made her debut as fan-favorite Montgomery in the Season 1 finale in 2005, teased the announcement on TikTok Thursday by participating in the viral “Questions I frequently get asked” trend.
While bobbing along to music, Walsh responded “YES” to the question: “Will you ever come back to ‘Grey’s Anatomy’?
The video then cuts to show Walsh in her white coat as she mouths the words, “Surprise, (expletive). I bet you thought you’d seen the last of me.”
“It’s really happening,” Walsh captioned the post. “Dr. Addison Montgomery will see you shortly”
Walsh shared the same video on Instagram, where Ellen Pompeo, who stars as Meredith Grey on the series, commented, “Lets give them what they want…..quality tv drama”
“It feels so good to be home again, joining Shonda, Ellen and the rest of the incredible cast on Season 18,” Walsh said. “Just wait until you see what she’s got in store for you.”
“Grey’s Anatomy” has gone through many cast changes since Walsh’s debut appearance. Her character Montgomery was spun off into “Private Practice,” which ran for six seasons from 2007 to 2013.
More recently, Walsh appeared in “Emily in Paris” alongside Lily Collins and also had notable roles in “13 Reasons Why” and “The Umbrella Academy.”
