The Keeping Up With The Kardashians stars joined the likes of Jennifer Lopez, Selena Gomez and Taylor Swift as they took to the red carpet for the lavish ceremony, held at the Nokia Theatre in Los Angeles.
Taking centre stage was Khloe, who proved there's nothing better than a little black dress as she posed up a storm in her sexy leg-flashing number.
Her dress was designed by Versus Versace and featured an asymmetric, thigh-skimming hemline with gold embellishment, plus a figure-hugging design to show off her famous curvy silhouette.
To go with her LBD, Khloe lengthened her sunkissed pins with towering patent courts, styling her ombre locks in an effortlessly tousled 'do while painting her pout a glossy mauve shade.
Meanwhile, half sister Kylie made a serious style statement in a satin burgundy red number complete with a low-cut neckline and thigh-high slit.
The youngest Kardashian-Jenner sister wore pointed black heels with cut-out mesh detailing and tucked her turquoise dip-dyed barnet into a low-slung bun, leaving strands loose at the front to help frame her face.
And Kendall looked incredibly glamorous in her getup too, sporting a mesh halterneck number with a sky-high slit running up the front, accessorised with a simple pair of diamond earrings.
Kendall - who was recently snapped up as the face of cosmetics giant Estée Lauder - nailed things on the beauty front, teaming flawless skin with metallic silver eyeshadow and dainty feline flicks, adding a touch of bronze to help warm her cheeks while slicking her pout with fuss-free nude gloss.
Of course it was only fair all three ladies looked positively stunning at the event, as they took to the stage later that evening to present an award, announcing Katy Perry as the winner of the Favourite Pop/Rock Female Artist category.
The reality stars attended the high-profile event without pregnant sister Kourtney and Kim, who has been busy promoting her new fragrance, Fleur Fatale, and is currently enjoying some time with friends in Abu Dhabi.
