Ed Sheeran and Taylor Swift duet on the stunning 'Lego House.'

It's no secret that Taylor Swift and English singer-songwriter Ed Sheeran have been on their collaboration tip. Ed is slated to pen songs for Taylor's forthcoming album, and in the meantime, Taylor wants the world to know that they're also eating cheeseburgers. Productive.

You might imagine that Taylor and Ed are a singer-songwriter match made in heaven -- now we have proof that they actually are. Though we've yet to hear one of their co-penned originals, Taylor did post a Viddy of the two of them harmonizing on Ed's song, "Lego House." Umm, prepare yourselves because it is VERY special -- sitting on the floor of what looks like Taylor's kitchen (why not?), Ed strums the guitar and sings the hook while Taylor casually pops in on the harmony line. Maybe it's the beauty of the original song or the way their voices blend, but all it took was a lil' 15-second video of these two and our faces are fully melted off. Totally worth it, IMHO.
