The cobra is out of the bag. With millions binged through the latest season of Netflix’s Cobra Kai, audiences got a surprise appearance from seven-time Grammy Award winner Carrie Underwood.

The country singer performed “The Moment of Truth” from The Karate Kid original soundtrack in the series. Of course, we won’t spoil how it led to this event, but you probably could figure it out.

“I grew up watching ‘Daniel’ and ‘Johnny,’ and I can’t believe I actually get to be a small part of the legacy that is The Karate Kid,” she stated in a press release. “Once I discovered Cobra Kai a few years ago, it became one of my favorite shows! I had so much fun being on the set and singing such a classic song. I cannot wait to watch every new episode!”
