Though she wasn't even nominated for an award, Miranda Lambert stole the show at the 2014 Billboard Music Awards on Sunday, May 18. The country crooner, 30, turned heads in three different outfits. 

Lambert arrived at the Las Vegas awards show in a poppy pink Georges Hobeika body-conscious dress. The sleeveless number showed off Mrs. Blake Shelton's cleavage with an angled sheer panel down the chest. She accessorized the dress with a pair of black heels. 

The singer hit the stage with fellow country artist Carrie Underwood during the show. The pair debuted their new duet "Somethin' Bad," off of Lambert's upcoming album "Platinum." 

She went edgy for the performance, wearing a distressed rock tee under a studded leather motorcycle jacket. On the bottom, she wore an orange-red leather skirt with hardware on the hem over a pair of fishnet stockings. She accessorized with a fingerless leather glove, a large cocktail ring, and armfuls of bracelets. 

Lambert's third look was much more toned down. She spoke onstage in a chic black jumpsuit, which featured spaghetti straps and a sweetheart neckline. She incorporated color into the outfit with a pair of hot pink peep-toe ankle-strap heels.
