Kylie Jenner and Tyga appear to have been working on not just their relationship but also a collaborative project.

The “Keeping Up With the Kardashians” star and the rapper will reportedly be releasing a calendar. A source told Us Weekly that the photos Jenner posted in celebration of Tyga’s birthday are just a couple of the ones that will be included in their project.

In the photos, the two are seen topless in a room with concrete walls. There is also another photo posted by Sasha Samsonova, who shot the pictures, wherein Jenner is lying on Tyga’s bare stomach.

Jenner and Tyga have yet to comment whether there is truth to the story or not.

The two have been dating for two years now. Their relationship started when Jenner was only 17 years old. The reality star admitted in an interview with Complex that many people told her to not get associated with Tyga when they first started “hanging out,” but Jenner maintained that their relationship just came naturally.

“I still get comments like, ‘Don’t be with him,’” Jenner said. “But we’re not doing it for the public — we love each other. We need to be together at all times. We never get mad at each other, we just figure things out.”

Jenner wasn’t the only one who received a warning about pursuing a relationship. Tyga was also reportedly asked by friends to not be with Jenner. The couple, however, decided to push through with their relationship, and nowadays they seem to be getting serious.

In September, Jenner revealed on Snapchat that Tyga gifted her with a huge diamond promise ring. Describing the present, Jenner said: “If this is my promise ring I wanna know what my engagement ring gonna look like [sic].”

Rumors about Jenner and Tyga’s relationship started swirling in 2014. They kept the romance under wraps until September 2015.
