From Orange County to "Nashville," Rachel Bilson and Chris Carmack have come a long way.

The two actors both starred in the teen drama "The O.C.," which ran from 2003-2007. Recently, Bilson joined the cast of CMT's "Nashville" and reunited with her former castmate, who plays gay country singer Will Lexington.

Bilson shared a photo from the set and referenced Carmack's most famous line from "The O.C.":

"Nashville" aired its season 5 midseason finale last week, and the show announced Bilson and "Empire" actress Kaitlin Doubleday would be joining the cast for the second half of the season in the wake of star Connie Britton's departure. Details of their characters were not revealed, but Bilson reportedly has a major role involved with country music label Highway 65.
