She also claimed Top Digital Songs Artist, Top Country Artist, Top Country Album for Red, and Top Country Song for We Are Never Ever Getting Back Together, while she beat Justin Bieber, One Direction, Adele and Mumford & Sons to take home the title of Top Billboard 200 Artist. Rihanna and Gotye were also quadruple winners heading into the event, while other winners in the pre-show announcement included One Direction, Madonna, Justin Bieber and late singer Jenni Rivera, who claimed two awards in the Latin categories. Meanwhile, inside the MGM Grand Garden Arena, Nicki Minaj became the first big winner of the ceremony itself, walking away with Top Rap Artist after Bruno Mars helped to kick off the awards with a performance of Treasure.
