In a Vine video posted by a fan who met the band at One Direction's book signing in London on Dec. 10, Niall can be heard singing Taylor's song "Out of the Woods." You can clearly hear him sing the song's chorus, "Are we out of the woods yet, are we out of the woods yet, are we in the clear?"
He's totally playing around when he's singing the song, so we don't think it really has anything to do with Harry or is a Taylor diss. It seems like he's just really a Tay Tay fan.
We're sure the guys really gave Harry a hard time when that one came out, so maybe it was just in his head at that given moment? Maybe a fan was wearing a T-Swift t-shirt and it reminded him of that song? Who knows, but the whole thing is pretty funny to listen to. Too bad it wasn't Harry caught singing the tune. Now that would be epic.
Watch the whole thing below. Do you think Niall was busted singing Taylor's song?
