Miranda Lambert poses with her four ACM awards backstage at the 46th annual Academy of Country Music Awards in Las Vegas April 3, 2011. Lambert won four prizes at the Academy of Country Music Awards on Sunday but lost the coveted entertainer of the year honor to Taylor Swift in a major surprise. Lambert retained her crown as top female vocalist and her wistful tune "The House That Built Me" was honored for single, song and video of the year at the 46th annual awards ceremony.
