James Corden Asks Harry Styles If 'Perfect' Is About Taylor Swift: His Reaction Is Everything

Bless James Corden for asking the hard hitting questions. During One Direction's sit down with James during their The London Session appearance, the host was very interested in just who the song "Perfect" is about.

Watch as he drops all the Taylor Swift references you can handle. The best part, however, is Harry's hilarious reaction.

James doesn't mince words when asking Harry about "Perfect" by saying: "And in this line it says, 'And if you're looking for someone to write your break up songs about, baby I'm perfect.'"

He adds, "Now listen, I don't want to have any bad blood about this...and if this is a problem, we don't have to talk about it. We can just shake it off."

Finally, James gets to the point: "Who's this song about?"

So. Friggin'. Cheeky. James' teasing is hilarious, but we can't get enough of Harry's adorable facial expression during the line of questioning.

Notice he says nothing, but that smile says so much.
