Shelby Z Nails Carrie Underwood’s “Last Name” On American Idol [VIDEO]

Meet Shelby Z from Alabama.  She's a hairdresser...for now.  Just listen to this girl as she kills her audition on American Idol.

I said "meet Shelby" but there's a chance you may have seen her before.  Remember this Blind Audition from The Voice in 2013?
