Grey's Anatomy is known for its stellar guest stars, and it looks like Season 11 is going to be no exception. We already know the legendary Geena Davis is settling in for a major arc, and now it looks like The Americans star Annet Mahendru will also be making a guest appearance.

Last week, Annet herself tweeted the news, writing, "Had fun @GreysABC today ;) #greysanatomy."  


OK, so that's not much to go on. We do know she'll be in at least one episode and she had fun on set (doesn't everyone?), but that's about it.

TVLine confirmed the news, and added a tiny bit more info, indicating that Annet's role will be a one-off. That probably means she'll play a patient, or someone related to one, since new docs in the hospital normally last more than one episode, even if they are only visiting. Though we suppose she could also play one of the doc's relatives.

Whatever the case, we're excited to see what Annet — who earned a Critics Choice Award nomination for her work on The Americans — brings to the table when she stops by Grey Sloan Memorial.

Are you excited for Annet to be on the show? Let us know in the comments below!
