Miranda Lambert had a great night last night. The country superstar was nominated for seven Academy of Country Music Awards, and she took home the most trophies of the night. Lambert won four total: Female Vocalist of the Year, Song of the Year, Single Record of the Year and Video of the Year. Talk about bragging rights! For her walk down the red carpet, Lambert made a romantic choice with a cap sleeve gown with a jeweled waist from Lorena Sarbu's spring 2011 collection—a nod to her upcoming nuptials to fellow country crooner (and ACM Awards co-host), Blake Shelton. "I loved my red carpet dress because I'm feeling bridal," she told InStyle. "And it was white!"
