In the video, the two are seen sharing some sweet moments, kissing and laughing together.
The couple, rumored to be dating since last fall, kept their romance on the down-low while she was underage. They have become less discreet since Kylie turned 18 earlier this month, and made their public debut as a couple in the audience at last night's VMAs.
In the song, Tyga seems to reference Kylie by rapping, "They say she young, I should've waited / She a big girl, dog, when she stimulated."
"Stimulated" is part of Tyga's new mixtape "F*k Wat They Talkin Bout," which dropped August 24.
