It looks like Kylie Jenner and Tyga are officially back on.

And how do we know this, we hear you ask?

Snapchat, obvs.

The 18-year-old Keeping Up With The Kardashians star posted a photo of photo booth snaps (yup, she’s just as basic as the rest of us), which showed her and Tyga kissing and generally being super cute together.

The pictures were taken from Khloe Kardashian’s 32nd birthday on Monday.

And if sources are to be believed, the two are more than just loved up photo booth dwellers.

Speaking to US Weekly, an insider revealed that Tyga has moved into her swanky new LA pad.

They said: “They are officially back together and he is staying there with her.

“It's up in the air if he is going to live there permanently or is just staying there for now.”

The two split earlier this year after almost two years together.

It would seem these two can’t stay away from each other!
