Their relationship has had its fair share of ups and downs.
But Kylie Jenner and Tyga were packing on the PDA in a promotional video for designer Alexander Wang, which she posted to her Instagram account on Monday.
The 19-year-old reality star turned up the heat in a sexy display, with the 26-year-old rapper kissing her neck.
Seductively leaning against a wall and closing her eyes, the brunette beauty enjoyed the attentions of the tattooed ex-boyfriend of Blac Chyna, whom she has been dating on-off for over a year.
The action in the video goes from the corridor into a lively hotel room, with Kylie flashing her legs in a thigh-skimming black skirt.
She added a strappy black vest top, which clung to her curves.
No wonder Tyga gave her admiring glances as he relaxed in an empty bath tub. Skrillex, 28, joined the glamorous models in the slow motion stylish party scenes.
The reality television star has recently bleached her tresses a peroxide blonde hue, so this appears to have been filmed when she was still dark-haired.
With her fluttery dark lashes, defined brows and contoured cheekbones, the lip kit mogul had undoubtedly taken time to perfect her beauty look.
Keeping with the less is more theme that Wang is known for, the scantily-clad models partied in the lavish hotel room.
Earlier this month, Kylie and Tyga were FROW for the Alexander Wang show in NYC alongside Madonna and Nicki Minaj. Check out the video as the couple have fun making the Alexander Wang fashion video below.
