Ed Sheeran may not be dating Taylor Swift, at least, that's what he says, but that doesn't mean he can't sing her songs.

While appearing on an Australian radio show recently, Ed performed an acoustic version of Taylor's hit "I Knew You Were Trouble," as part of a bit where guest artists perform the beginnings of popular songs, and then they start the real version up later on.  Considering the stories that have gone around lately about him and Taylor, it's surprising that Ed agreed to sing the tune, but it's actually pretty awesome, and so far, fans have been enthusiastic, saying it's better than Taylor's original.

It remains to be seen whether or not Ed and Taylor will perform the song together when she launches her Red tour next week, and he tags along as the opening act.
