Kylie Jenner just can't keep her hands (and mouth) off Tyga.

After making their relationship fashion week official , the couple spent their Saturday night at Alexander Wang's afterparty at Pier 94 in New York where they packed on the PDA. And of course, since everyone's so obsessed with recording every waking moment of their lives (pics or it didn't happen!), the youngest member of the Kardashian-Jenner krew made sure to share a Snapchat video while kissing her man at the party .

In the video, the 18-year-old is seen grabbing the 25-year-old rapper's face and seductively biting his lip. Oh, and she makes sure to look straight at the camera while doing it, seemingly telling us that she doesn't care what anyone thinks (thank you very much) without even saying a word. Naturally, in reaction, Tyga shows off his golden grills.
