Being pretty talented in the vocal department, it might seem like quite an honour to be sung to by X Factor USA girl group turned international popstars, Fifth Harmony.

Here's a helpfully labelled pic of the girls, just in case you were confused as to their identity:
OK, so the Fifth Harmony girls didn't actually hang out under a load of celeb's balconies just waiting for an opportunity to serenade them (although we wouldn't put it past Camila if Zayn Malik was involved) and instead decided to make a few celeb's tweets into a musical version for MTV this week.
