Actress Sandra Oh will be exiting Grey's Anatomy after being a series regular for 10 seasons.

Just a few weeks ago, Oh tweeted messages from the set of Grey's anatomy shooting her final moments.

On April 21, she tweeted: "I've been dreaming nonstop about Grey's for the past few weeks. Can't believe it's my last week here already."

The actress also tweeted a photo of her trailer with the caption, "slowly wrapping out my trailer!"

An older tweet back in April 11 shows a selfie of Oh and co-star Kevin McKidd stating, "shooting one of our last scenes. :("

Fellow co-stars are clearly sad to say farewell to Sandra Oh. Last week, Ellen Pompeo tweeted a photo of herself and Oh to Instagram with the caption: "So proud of the work we've done together @iamsandraoh, We've laughed we cried we've kicked some serious acting ass together #SOGRATEFUL."

This week's episode of Grey's Anatomy season 10 will see the return of Isaiah Washington reprising his role as Dr. Preston Burke.

The title of the upcoming episode, "We are Never Ever Getting Back Together," hints at the some sort of reunion between former couple Christina Yang and Preston Burke.

In the promo video for Grey's Anatomy season 10 episode 22, flashbacks are shown of Cristina Yang preparing for her wedding before being heartbroken by Preston Burke, who says, 'I'm sorry."

"It's the reunion seven years in the making," the narrator says in the trailer. "I want you Cristina," says Burke. "All you have to do is say yes," to which Cristina replies, "I don't know."
