The 18-year-old reality star shared the moment on Snapchat, which shows her kissing her rapper beau on the lips inside the party’s photo booth.

Kylie’s sisters, Kim Kardashian, Kendall Jenner and Khloe Kardashian, wore sparkly dresses for the swanky birthday celebration, while the oldest Kardashian-Jenner sibling, Kourtney Kardashian, 36, opted for a dapper suit to channel Jay Gatsby himself.

The birthday girl, Kris, donned a floor length silky white gown and a fur shawl, which she wore over her shoulders. The Kardashian montriarch paired the outfit with a diamond-incrusted headpiece and long diamond necklace.
