Kylie Jenner and Tyga -- No Doubt ... Back Together (PHOTOS)

Kylie and Tyga made Kanye's music video roll-out their coming out as they showed up Friday night at The Forum for the big event.

This is probably not sitting well with some of her brood, but Kylie clearly wanted back.

Tyga made that clear Friday when he posted a pic of Kylie ... and when you connect the dots they were obviously already together.
