Carrie Underwood starred in a Nashville-themed version of “Undercover Sing” on Tuesday’s (11/12) Jimmy Kimmel Live.

Carrie set up in the back of a boot store. As customers came in, the store workers asked them questions. They revealed enough details for her to sing a personalized song to them over the loudspeakers.

As Carrie sang, the customers were confused until she came out to greet them and revealed the prank.

You can see more of Carrie Underwood as she hosts the 53rd CMA Awards Show along with special co-hosts Reba McEntire and Dolly Parton tonight (11/13) at 8/7 central on ABC.
