Long-time Grey's viewers will remember that Kate had a main cast role on the show in seasons two and three after being introduced in the season one finale as Patrick Dempsey's character's estranged ex-wife. After her time on the show came to an end, creator Shonda Rhimes continued Addison's story on spinoff show Private Practice, which saw her move to Los Angeles to start anew.

The actress, who is also known for her roles in The Umbrella Academy and 13 Reasons Why, last appeared in Grey's Anatomy back in 2012, while Private Practice ended after six seasons in 2013.

The exciting news comes weeks after show bosses confirmed that Kate Burton, who plays Meredith's mother, will also be making "multiple" appearances in the new run of episodes. 

While Ellis Grey, who suffered from Alzheimer's disease, died back in season three, the Scandal actress has made many appearances on the show since then through both flashbacks and dream sequences. She was most recently seen in season 15 when she appeared to Meredith in a dream.

As HELLO! previously reported, it seems more likely that this time around, she'll be appearing through flashbacks as Meredith has now woken up from her Covid-induced coma from season 17, which saw her reunite with other departed stars such as Patrick Dempsey and Eric Dane.

The premiere episode of Grey's Anatomy season 18 will also introduce viewers to a new character, Dr Alan Hamilton, played by The O.C.'s Peter Gallagher. If that wasn't enough, it will feature a crossover with spinoff show Station 19, meaning that viewers can expect an action-packed hour of TV!
