The on-again, off-again couple Kylie Jenner and Tyga are officially on-again according to the youngest Jenner's snapchat stories.

The 18-year-old posted photo booth pictures from older sister, Khloe Kardashian's 32nd birthday party of her and Tyga kissing and being quite adorable.

And the Snapchats didn't stop there as the two were out and about on Tuesday shopping for luxury cars ... as if they don't own enough already.

Jenner's Snapchat story followed the 26-year-old Tyga through a Bugatti dealership.

If those snaps alone weren't proof enough, the Keeping Up With The Kardashians reality star also uploaded her hand on top of the "Rack City" rapper's wrist with matching diamond-encrusted watches.

The two were said to have broken up for good in May and Jenner was even featured making out with another rapper in his music video, so time can only tell how long these two will be back on for.
