This has to be the best prank!  A nice prank is a nice warm up to the CMA Awards!  Carrie Underwood has a beautiful gift for singing songs that really relate with people, but she took that gift to a bigger level Tuesday night on Jimmy Kimmel.

Carrie performed a few personalized ballads for a few unsuspecting fans when they least expected it on Tuesday!

Jimmy Kimmel set up this little prank just in time for her duties as Co-Host of the CMA’s tonight!  Carrie was stationed in the stock room of a Nashville boot store.  Shoppers browsed and checked out the selection in the boot store. As they browsed, Carrie watched hidden camera footage and listened in as they revealed little personal details that Carrie would sing  those details to the tune of “Before He Cheats.”
