What do you think of the Grey's Anatomy star's new look?

Fans have a lot to look forward to when the Ellen Pompeo-led series returns to screens on Thursday 30 September. Earlier this month, show bosses confirmed that several former stars will be returning for the premiere episode, including Abigail Spencer, who played Dr Megan Hunt. 

Kate Walsh, who played Patrick Dempsey's character's estranged ex-wife, Dr Addison Forbes Montgomery, will also be back for multiple episodes of the upcoming season.

Additionally, Kate Burton, who plays Meredith's mother, Ellis Grey, will also return. Audiences will remember that she suffered from Alzheimer's disease and died back in season three, but 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.

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!
