Hailey, 25, is married to pop singer Justin Bieber and has modelled for several famous brands including Guess, Ralph Lauren, and Tommy Hilfiger.
The star looked fashionable in a pair of black, high-waisted pants with transparent, flower patterned tights underneath.
She paired them with a white crop top and black leather jacket, giving some edge to the look.
Hailey accessorised with a pair of dark sunglasses and a couple of gold rings on her fingers.
She completed the look with a pair of pointed black heels with sparkling buckles.
Hailey was joined on the carpet by Batman actress Zoe Kravitz, who looked chic in a black semi-sheer top and blue jeans.
Spiderman actress Zendaya also stunned in black at the event in figure-hugging floor length dress, which she accessorised with bangles and large hoop earrings.
Zendaya stars in Dune, which is up for a number of Oscar awards tomorrow night.
