0812_kylie_jenner_birthday_photos_launchKylie Jenner‘s 18th birthday party almost got really, REALLY awkward when her parents ended up in the same booth … with Kris Jenner‘s boyfriend!

We got these pics from inside Sunday night’s bash at Bootsy Bellows — and you can see Kylie, her sisters and their significant others all having a great time. But poor Corey Gamble … at one point in the evening he became the meat in a Kris-Caitlyn Jenner sandwich.

Outside of that moment, looks like everyone had a blast. Especially Tyga.
