Who knew that Carrie Underwood was a bit of a prankster? Obviously the country superstar is in Nashville this week for the 53rd Annual CMA Awards.

So, Jimmy Kimmel decided to take advantage of this for a bit on his show called Undercover Sing. Carrie hid in the back of a boot store and sang to shoppers who had no idea what was going on.

She could barely keep it together at one point while singing about ostriches, which was pretty hilarious.

Check out the video below.
