Of all of his roles, Nashville's Will Lexington is probably one of Carmack's sweetest. It's also the role that Carmack held onto the longest — the part spanned over a period of six consecutive seasons, ending in 2018. In the country musical drama, Will is a closeted gay singer-songwriter who eventually comes out to the country community and his family. Carmack's character is charming and caring to his partners and friends, a complete 180-degree flip from the actor's smarmy bad boy roles.
