Kylie Jenner I'll Get the Check ... Billionaire Celebration with Caitlyn

Kylie Jenner's getting some love from her, no doubt, incredibly proud papa -- as they celebrate her huge financial milestone with a fancy dinner in Malibu.

Caitlyn Jenner hugged it out with her daughter Friday night outside Nobu. We're guessing they hooked up to raise a glass to Kylie for officially reaching billionaire status, according to Forbes ... at just 21 years old. Yes, she's also the world's youngest self-made billionaire ever.

The father-daughter dinner came complete with a third wheel -- Caitlyn's partner, Sophia Hutchins, and the loving family scene at the end of the meal raises just one question.

We've all been there ... that awkward moment when you're a working adult and go out to dinner with a parent. WHO picks up the check??

Y'know Caitlyn had to offer -- after all, her net worth is reportedly an estimated, and totally respectable, $100 mil. She's used to paying, but maybe juuust this once ... ya let the kid slap down her black card.

It's Kylie's time to shine.
