This year, the big award show was a night to remember thanks to the speeches that were given, the performances that happened (cough, the Jonas Brothers, cough) and of course the fashion.
While we have our favorites, see Swift's pastel purple RaisaVanessa mini dress or Priyanka Chopra's Zuhair Murad white gown with Tiffany & Co. diamond jewelry, we really want to know which star you thought looked best in Las Vegas at the event.
Were you a fan of the Jonas Brothers, who color-coordinated their stripped suits? Or, were you a bigger fan of Cardi B's Cher-inspired yellow two-piece ensemble?
What about Sofia Carson's lavender, ruffled gown by Giambattista Valli from the Haute Couture 14 collection?
We also loved seeing Eva Longoria on the carpet especially since she showed off her killer legs in a black cocktail dress with pleated top and crystal belt by Alberta Ferretti.
Oh, and how could we forget Julianne Hough's sparkly number by Genny, which consisted of a bikini top, hot pants and a matching blazer? It was gorgeous.
Last, but not least, was Ciara. The singer donned a sexy black gown, with a sheer neckline by Stephane Rolland and had her son, Future Zahir, as her date wearing a snazzy Versace outfit.
