Q&A: Chris Carmack on Playing Gay in Country, Pop Music and 'The O.C.'s' Legacy 

Carmack, who stars as openly gay country star Will Lexington on the ABC drama, recently broke into the world of pop music with his independently released EP, Pieces of You. Last year, the former star of The O.C. told ETonline, "I've always been performing music and writing songs and recording songs, but on a very small-scale operation. It wasn't until I became involved with Nashville that I thought I had opportunities to record my music in a way that I would want to put it out into the world."

As a talented musician in her own right, Slaver has performed alongside her future husband at the Opry and even played a backup singer for Hayden Panettiere's Juliette Barnes on Nashville!

Congratulations to the happy couple!
