Kylie Jenner and Tyga tried to keep their relationship out of the public eye for months, but now that she's 18, they're free to do what they want. We haven't seen much PDA from the couple, but Tyga's new music video for his song "Stimulated" is what fans of the couple have been dying to see ever since the dating rumors started.

The video shows the 25-year-old rapper writing down lyrics as Kylie enters the Malibu mansion, and from there on the two are all over each other as he raps the song, which is most likely about her, according to Entertainment Tonight. The lyrics are about Tyga having sex with a young girl, and now that they've made it very clear their relationship is for real, it's obvious the song is about the 18-year-old reality star.

"They say she young, I shoulda waited / She a big girl, dog, when she stimulated," he raps. "F--k what they talkin' about, I do what the f--k I wanna do." From there on the lyrics just get more and more sexual as the video shows the two sharing an intimate moment on the balcony.

Just last night, the two attended the MTV Video Music Awards together. While they weren't seen too much on camera, they were sitting next to each other, according to Us Weekly. Kylie presented an award and wore a mini champagne-colored Balmain dress and even rocked some bangs. Tyga was featured in a skit with host Miley Cyrus and was more dressed down in a graphic T-shirt, shorts and a black vest.
