Fifth Harmony & One Direction
Back when both X Factor groups were five piece acts, 5H expressed their collective Directioner fandom after meeting the boys at the Teen Choice Awards in 2013. "One of the best moments of the night!!!!" they captioned this Instagram photo. The more exclamation points, the stronger the fangirling.
