That's exactly what went down in a new mashup that's just made its way online. YouTuber Kate Parkin created magical "Harry Potter"-themed Tay Tay awesomeness. We are kind of obsessed.
Kate also known as weasleysweaters on YouTube, took several songs off Taylor's 1989 album and changed the lyrics to reflect "Potter" story lines and themes. Taylor's not doing the singing, though. The tunes are all sung by Kate, and are from the perspectives of different characters in Potter-ville. Sweet costumes are involved, too.
Check out Kate's Harry Potter and T-Swift creation below. Pretty friggin' awesome, right?
