In the NSFW video, Jenner, 18, has her legs wrapped around her beau's torso and films him as he says: "I don't f--- with nobody, I don't f--- with nobody. It's just me, my fiancée, this little dog I just got. I don't f--- with nobody."
Though it may seem like the hip-hop star is insinuating the couple is engaged, a closer look at Tyga's social media shows that he simply seems to be quoting a video of rapper Logic, which Tyga, 25, posted to Instagram earlier in the day.
In the (also NSFW) video, Logic says during an interview: "I don't f--- with nobody, yeah I don't f--- with nobody. Like, at all. Nobody. So, it's very simple. I stay at my house. It's just me and my homies and my fiancée and my little puppy I just got. I don't f--- with nobody, I don't go anywhere, I don't go to parties, I barely go outside."
Tyga captioned the video: "All day" with a "crying tears of laughter" emoji.
Jenner first sparked engagement rumors in July when she uploaded an Instagram of herself wearing a sparkly diamond ring and captioned it "king kylie" – Tyga calls himself "King Gold Chains" and stars in his own reality show on MTV, Kingin' with Tyga.
She shut down the rumors July 30 by tweeting, "Not planning on getting married anytime soon :)," but speculation didn't stop as Jenner continued to wear the diamond ring.
Since Jenner turned 18 in August, the couple certainly hasn't been shy about PDA, vacationing together in Mexico and St. Barths, as well as kissing in Tyga's "Stimulated" music video, which feature R-rated lyrics likely about Jenner.
Tyga also posted steamy pictures of his girlfriend on Instagram, and Jenner documented their nights in – and out! – on Snapchat.
