Grey's Anatomy season 19 minor spoilers follow.

Grey's Anatomy has confirmed the return of Kate Walsh in season 19.

Show bosses are bringing back the fan-favourite cast member as Addison Montgomery, following the news that Ellen Pompeo is going to be taking a limited role going forward.

Walsh most recently appeared in a few episodes throughout season 18, but Variety reports that she'll be back in a recurring capacity for this latest stint.

Fans will first see Addison in episode three, and then sporadically throughout the rest of season 19 as part of a continuing story arc.

The actress shared the exciting news with her fans on Instagram with a brief video revealing she was already back on the Grey's Anatomy set.

"Season 19 Baby. Here We Go," she wrote on Instagram.

Last season, a transplant patient brought Addison back to Grey Sloan to reconcile with Meredith (Pompeo) and finally grieve the death of her ex-husband Derek (Patrick Dempsey).

Fans are likely to be excited to see a classic cast member returning, along with an influx of new cast joining the show given Pompeo's reduced role.

Pompeo is expected to appear on camera in eight of the 23 episodes ordered by ABC for season 19, in addition to continuing to narrate the series.

The actress had previously suggested she was working with the writing team on ways to continue Grey's Anatomy without Meredith at the centre of the series.

With this limited role, Pompeo will now have time to produce and star in a Hulu series about a couple who start to have doubts about the young girl they have adopted.
