Ariana Grande trailed behind with six, while Pharrell Williams and 5 Seconds of Summer scored five nods. Iggy Azalea, Eminem, Nicki Minaj, One Direction and Sam Smith earned four nominations apiece. Voting in all categories is open at mtvema.com until Nov. 8. The MTV EMAs will air live the following day at 7 p.m.
