The 2013 Billboard Music Awards, which were hosted by Tracy Morgan, took over the MGM Grand in Las Vegas on Sunday! The stars hit the red carpet to kick off the night and then made their way inside to get the fun started. Bruno Mars stuck to his usual suited-up look in a red ensemble to open the show, while Carly Rae Jepsen, who won top digital song and two other honors, debuted hair of the same hue when she took the microphone to announce Icona Pop's performance of "I Love It." Shania Twain handed out the first statue of the evening to Nicki Minaj, who won top rap artist, while Selena Gomez took the stage to perform "Come and Get It." Tracy had a little fun in front of the audience by challenging Psy to a dance off while Macklemore and Ryan Lewis teamed up to sing their top rap song, "Thrift Shop."
Taylor Swift — who picked up six awards before the show even started and two more, including artist of the year, during the broadcast — was another of the evening's performers, belting out "22" after walking the carpet in a bright blue Zuhair Murad dress. Other big winners included Rihanna and Gotye, each with four trophies, as well as Justin Bieber with the milestone award.
