On Thursday (July 26), CMT's Nashville will close out its final season with the show's series finale episode. In addition to depicting the personal and professional lives of a set of fictional country artists and music industry executives, the TV drama has bridged the gap between its fictional country music universe and the real one with a number of cameos from real-life country artists.

Throughout its tenure, Nashville featured a number of interesting guest stars, including First Lady Michelle Obama, TV host Trevor Noah and music icon Steven Tyler. But the most exciting appearances were often from the real-life country music stars who popped up from time to time and helped make Nashville such a hit show.
