The adorable girl group was spotted jamming out on the couch to 1D's latest single Story of My Life when the camera panned over to show the guys actually singing the song!

Can we just say they sound AH-MAZING with just a guitar, their seski voices and the table of course!
Ch-ch-check out the adorable video (above)!!
