Jennifer Lopez always brings it on the red carpet, but at the 2014 Billboard Music Awards, she upped her game.

J.Lo showed off her long legs is a sheer red gown that opened up to reveal a skintight leotard. The singer also showed off her cleavage, as the dress sported a plunging neckline. However, yards of billowing chiffon kept this look classy and elegant.

As always, Jennifer's styling was on point. Her thick hair was blown out, curling ever-so-slightly at the ends. Her makeup was simple, save for a subtle smokey eye and an all-over glow. In short: She rocked it.

Ever the red carpet pro, J.Lo added a hint of shine with a cuff, clutch and metallic sandals.
