Martin Henderson has left Grey's Anatomy after two seasons in the role of Nathan Riggs.

If you watch Grey's Anatomy online, you will already know that the character appeared to get a happy ending with his former love, Megan Hunt.

Megan went missing ten years before, and only recently returned to his life after being found. It seemed like Nathan and Megan's relationship was not going to work after everything they had been through.

However, they defied the odds and moved to California to start a new life together with Megan's adopted son, Farouk. If you were watching the episode and wondering how Nathan would play into the show going forward, then you need not question any longer.

Series creator, Shonda Rhimes took to Twitter to confirm that Henderson's two-year tenure with the sudsy medical drama was over.

"I loved that we were able to give Riggs a happy ending worthy of his character and talent. As for Martin, this is not an ending for our relationship," she shared.

"He has been part of the Shondaland family since the pilot of Inside the Box, and he will always be family. I can’t wait to find a new project to work with him on in the future.”

Henderson originally debuted on the show during Grey's Anatomy Season 12 in the aftermath of Patrick Dempsey's exit. Nathan served as a love interest for Ellen Pompeo's Meredith Grey, but Meredith stepped aside when Megan returned.

With the news that Henderson is out of the show comes the news that another guest star has been cast.

According to The Hollywood Reporter, One Tree Hill actress Bethany Joy Lenz has been added to the cast in a guest arc as a character named Jenny.

No other details were given about the character, but we will wait for as long as it takes to see Bethany on the show.

Bethany was originally a cast member on fellow Shondaland series, The Catch, but the show went in a different direction after the pilot, and the actress was let go.
