Why were Niall Horan and Zayn Malik crying during their Glasgow concert?
We warn you though--it may bring a tear to your eye too!
Niall and Zayn were visibly emotional during the performance of "Little Things," with Niall starting to cry during his solo, then shaking it off with the most adorable shake of his head.
Zayn's eyes teared up as well while he sang...so sweet.
It's nice to know that despite singing "Little Things" a million times over, they still get caught up in the emotion of the lyrics.
What do you think of Niall and Zayn crying?
