Kristen Kelly, whose current single is "Ex-Old Man," will release a self-titled EP on Oct. 30 on Arista Nashville. The upbeat track is No. 30 on Billboard's country airplay chart this week. Kelly co-wrote the song with Paul Overstreet. She also co-wrote all four songs on the EP. "I am so excited to share more of my new music with my fans," she said. "This music is a culmination of years of blood, sweat and tears. Every song is a chapter in the story of my life."
