Alicia Keys' 40 Principales Awards Outfits Were Smart And Stunning

Alicia Keys certainly is a girl on fire! After matching FLOTUS in red at the Inaugural Ball and singing for the president, the stunning superstar spent her birthday in Madrid and she did not disappoint, donning not one but two chic sheer outfits.

The singer turned heads in a retro dress that featured a skin tight, hip hugging bottom and a sheer bodice. And just when we thought the 32-year-old couldn't steal our hearts any more, she took her look from glam to rocker chic, swapping the dress for fitted trousers and a sheer crop top with black bra underneath.

Keys also rocked the stage, singing hits from her new album including "Girl on Fire" and "Brand New Me." She was also honored during the ceremony, and even got serenaded by the crowd who sung her "Happy Birthday." Alicia is clearly showing us that she is still on fire no matter what age.

Check out pictures of the star's outfits and performance below.
