Sandra Oh made history this year by becoming the first Asian woman to earn an Emmy nomination for Outstanding Lead Actress in a Drama Series, and her Killing Eve costars won’t be the only ones cheering her on tonight. At an Emmys party this past weekend, the actress opened up about the support she’s received from her former Grey’s Anatomy castmates, too.

“You know, they know me. They really know me,” Oh, who left Grey’s in 2014 after 12 years of playing Dr. Cristina Yang, told Entertainment Tonight. “I know everyone is happy for me and [I] really, really appreciate their support.”

One of the people rooting for Oh is her former on-screen BFF Ellen Pompeo, who shared a pair of messages about the nomination via Twitter back in July.

“Yes!!! So incredibly happy for @IamSandraOh who deserves this more than anyone,” Pompeo wrote. “No one can touch this girl’s dedication to story telling or her talent. … I was not on my phone yesterday and clearly missed ALOT!!! Congratulations @IamSandraOh this is beyond well deserved and your history making is incredibly moving. Can’t wait to hear your speech!! Which will have us in tears and laughing at the same time I’m sure.”

Katherine Heigl, who appeared on Grey’s as Dr. Izzie Stevens from 2005 until 2010, also took to Twitter to congratulate her former costar, writing, “I felt an absolute swelling of pride yesterday when the Emmy nominations were announced and my old co-star and friend @IamSandraOh was on the list for a much deserved best actress nom for her incredible work on one of my new favorite shows @killingeve. Congrats my old friend!”

The 70th Primetime Emmy Awards, hosted by Colin Jost and Michael Che, airs tonight, Monday, September 17, at 8pm.
