Taylor Swift's recent forays have been all pop, but that doesn't mean a country twist isn't lurking in those tunes somewhere. 

Luckily, a queen of country, Reba McEntire, knew just what to do during Tuesday night's episode of Best Time Ever With Neil Patrick Harris: Sing a country-fied version of "I Knew You Were Trouble" in an old-style honky-tonk bar. 

While Swift is mum about her song inspirations for the tune, it's safe to say in this version Reba is plenty pissed at (or, at least, interested in) Cowboy NPH.
