The 19-year-old make-up entrepreneur was joined by the likes of her model sister and her friends Kendall Jenner, Bella Hadid and Hailey Baldwin.

While the Lip Kit founder rocked her party look in cropped black leggings with a strappy top complemented by a pair of beautiful black sky-high hill.

Kylie's elder sister Kendall Jenner turned heads with a white-coloured cropped T-shirt that had cartoon boob outlines etched on the front. The 21-year-old model, who is rumoured to be dating A$AP Rocky, styled her look with a pair of skin-tight leather trousers, green-high heels and chiffon shrug.

Kylie-Kendall's close pals Bella Hadid and Hailey Baldwin were also spotted attending the party. The Victoria's Secret supermodel Bella flashed ample assets while donning a sleeveless cream-coloured cropped top.

She completed her look with a cream cargo-style pair of pants and sunglasses. On the other side, Hailee was spotted wearing a very odd oversized hoodie in the party.

The Hip Hop star Travis was seen heading inside his party-donning joggers with a graphic T-shirt, jacket, and diamond jewellery.
