‘The O.C.’ costars Rachel Bilson and Chris Carmack reunite in ‘Nashville’

'Welcome to Nashville, b----!'

There was only one way Rachel Bilson should’ve been welcomed to the Nashville set, and it appears to have happened.

A few days after the news broke that the actress would be joining the season 5 cast of the CMT musical drama, she was reunited with her former costar from The O.C., Chris Carmack. And they took a photo together. And it has the perfect caption.

“‘Welcome to Nashville B****……this is how it’s done in Tennessee,'” Bilson wrote, tagging it “#propergreeting” and referencing Carmack’s unforgettable line in the pilot of The O.C.
