Kelsea Ballerini has fans wondering whether she not-so-subtly referenced Madelyn Cline on her newest EP, Mount Pleasant. "I always liked the color of my eyes 'til I knew she had brown / I'm green," Ballerini, 32, sings on "Emerald City," which dropped Friday, November 14. "Always liked my naive innocence 'til I learned she got around / I'm green." She adds, "If I got you, why does she still get me? / I hate to say it, but damn, she's pretty / Never known this shade of envy / Just tell me I'm your Emerald City.
