Rachel Bilson (The O.C., Hart of Dixie) and Kaitlin Doubleday (Empire) are coming to Nashville.

In recognition of the Nashies' unwavering support of the series, Bilson and Doubleday chose to announce the news directly to the fans on social media after the mid-season finale of Nashville Thursday (March 9) evening.

Nashville will also be a bit of a reunion for Bilson, who worked with series regular Chris Carmack on The O.C..

"We welcome Rachel and Kaitlin into our incredibly talented ensemble," said Marshall Herskovitz, executive producer and showrunner. "We fondly anticipate the second half of the season filled with surprising twists and turns that make Nashville so beloved by the fans."

Rachel Bilson was most recently seen as Dr. Zoe Hart in The CW's series Hart of Dixie, a fish-out-of-water story about a New York City doctor adjusting to life in a small Southern town after she inherits a local medical practice. Her film credits include The To Do List, Waiting for Forever, Jumper, L!fe Happens, The Last Kiss, and New York, I Love You. She also appeared twice as a guest star on the television series How I Met Your Mother, as well as Josh Schwartz's Chuck. Bilson also became an integral part of pop culture due to her series regular role on the popular television show The O.C. for four seasons.

Kaitlin Doubleday gained worldwide recognition portraying Rhonda Lyon on the megahit Empire. At age 17, she made her film debut opposite Leonardo DiCaprio in Steven Spielberg's Catch Me If You Can. Other notable screen credits include the cult classic Waiting, opposite Ryan Reynolds and Anna Farris, and Accepted, opposite Jonah Hill and Justin Long.

We can't wait to see what happens next on Nashville. Check out this teaser to see what's to come:
