I have yet to start up the new season of Cobra Kai on Netflix, but I had seen Carrie Underwood post something interesting on social (Exhibit A below).
In episode 9 of Season 4 the kids compete in the infamous "All Valley Karate Tournament" and Carrie shows up as herself to sing the 1984 Survivor Hit "Moment of Truth". She kids the kids some encouragement and makes note of her competitive nature and one of the adults even makes a comment about working on her husband Mike Fisher.
Have you stared to watch the new season of Cobra Kai?
