This is an old article, but we know Louis hardly can change his notes in acoustic songs (Drag Me Down Acoustic ver. Live is on YouTube now). He said himself he has tinnitus. Plus he was sick in that performance :< Poor Louis tho, I wish I could give you a hug T,T
Louis is just amazing. He has the best smile I've ever seen. I don't know why Harry was nominated for best smile instead of him. Don't get me wrong, I think Harry has a great smile. I just don't see why Louis' smile didn't get nominated for a TCA.
