Last night, country music’s biggest stars walked the red carpet at The Academy of Country Music Awards in Las Vegas. Female Vocalist of the Year and Album of the Year winner Miranda Lambert went Old Hollywood glam in a gold Randi Rahm halter, Taylor Swift accepted the Entertainer of the Year Award in a white J. Mendel dress with sexy side cut-outs, and Carrie Underwood posed in a pale lemon Abed Mahfouz gown. See their looks, as well as LeAnn Rimes, Sugarland’s Jennifer Nettles, Nicole Kidman, and more in the gallery!
