Kelsea Ballerini and Shania Twain are both featured in a trailer for the new ABC drama Doctor Odyssey. The show stars Joshua Jackson as Dr. Max Bankman. Kelsea describes her role as "guest star," which means that she is probably playing herself. Shania can be seen twirling around with Don Johnson. The show, which explores how doctors and nurses aboard a cruise ship navigate their professional and personal lives, premieres September 26th on ABC.
