The pair donned letterman's jackets with each of their initials and were seen stepping out of a Rolls Royce surrounded by smoke.
This is the second music video Kylie has starred in alongside her 25-year-old boyfriend. In August, they went heavy on PDA (and piggyback rides, naturally) in the video for the rapper's track, "Stimulated," which premiered just a couple of weeks after she turned 18.
The filming of the new video comes shortly after Kylie and the majority of the Kardashian-Jenner clan -- including sisters Kim Kardahsian and Kourtney Kardashian and mom Kris Jenner -- were in Las Vegas to support Khloe Kardashian after her ex, Lamar Odom, found unconscious at a Nevada brothel and rushed to the hospital on Tuesday. He was placed in a medically induced coma on Wednesday, which he woke up from on Friday.
Kylie shared an old photo of her and Lamar on Thursday, followed by a cute video of the two doing the "stanky leg" together at a previous event. "Let's dance again together soon. Prayers up for Lamar please," she wrote on Instagram.
