Later that night, the two attended a birthday bash for Kylie’s BFF, Jordyn Woods, in Los Angeles, a source confirmed to ET. Kylie was spotted arriving shortly after sister Kendall Jenner. The 18-year-old sported a sexy backless white dress, while her sister kept things casual in a knit crop-top, black sweatpants, and boots.
Kylie also shared a video of her and Kendall from inside the party, which appeared to have a "white party"-theme, a dress code the ever-fashionable Kendall, 19, chose to ignore.
While the clip -- bizarrely captioned "the ostrich to my heart" -- has no sound, it’s pretty clear that the party was a wild one. Police broke up the festivities, which were held at the Watermarke Tower in downtown L.A., after responding to a noise complaint just after midnight.
The sisters departed separately after the cops broke things up, around 12:20 a.m., and Kylie and Tyga were seen driving Kendall to her car, which was parked in a different lot.
