Christina Aguilera looked svelte and stunning at the 2013 Time 100 Gala, where she was honored as an artist.
This is the best we've ever seen Xtina look -- no weird hair colors and no drag queen makeup! Her dress was simple with one super sexy feature -- a tiny keyhole just under her decolletage. Diamonds added that extra sparkle to an already amazing look.
Christina wasn't the only one who looked beautiful in black. Her former "Mickey Mouse Club" costar Justin Timberlake and his wife Jessica Biel wore the color, too. Olivia Munn was a ray of sunshiine in her yellow gown, while Lena Dunham disappointed in a drab dress and chintzy belt.
