One Direction stole the show during Sunday's Billboard Music Awards [1] — without even performing. They accepted the first award of the night, top duo/group, and thanked Zayn Malik, who famously left the band in March [2]. "This one is for the fans," said Liam. "But there's one more person to share this with, and it's our brother Zayn, so thank you." Cue the millions of One Direction fans worldwide letting loose a single tear. Miss you, Zayn.
