Britney Spears [1] can do no wrong. The singer, who performed and was honored at the Billboard Music Awards [2] on Sunday night, made a jaw-dropping appearance when she stepped out on the magenta carpet looking like a real-life goddess. Not only did she show off her killer figure as she strutted her stuff for the cameras, but her see-through black lace Reem Acra ensemble definitely gave us nostalgia from her "Stronger" days. The hotness continued as she opened the night with an incredible medley of her greatest hits [3]. After bringing the heat on stage [4], Britney took to Instagram to thank her fans and reveal that all she wants now is "a cheeseburger." Bask in all her gorgeousness here!
