Country Music celebrated the 2011 CMT Awards last night! And it had some major star power. Nicole Kidman cheered on her husband Keith Urban‘s performance of “Long Hot Summer” in a green and brown Proenza Schouler ensemble from the label’s fall 2011 collection, which she paired with strappy lavender Pierre Hardy heels. Inside the event, the actress posed for a photo with Sheryl Crow, who was nominated twice in the Collaborative Video of the Year category (she didn’t take home the trophy, though). Crow walked the red carpet in a slinky white Catherine Malandrino gown accessorized with stacks of truquoise bangles and beachy waves.
