But, the night started with Kim, Khloe Kardashian, Kris Jenner and a bunch of Kim's friends boarding Kylie's private jet -- Kim's must be in the shop -- for a quick flight to Las Vegas where the gang planned to take in Usher's residency.
But when they got close to Vegas, air traffic control said it was unsafe to land due to extremely high winds -- gusts up to 60 MPH -- so, the pilot had to bang a U-turn and land back in Los Angeles.
Kim's party didn't stop though ... after hopping on a party bus, someone busted out the jello shots again -- looks like Kim had plenty -- and they ended up at an In-N-Out, naturally, for burgers.
And, wow, what a scene inside! Kim in a bikini top, and Khloe in a nude catsuit ... with the whole glammed-up crew standing at the counter ordering, just like normies. As everyone knows ... there's no VIP in the late-night fast food game!
The birthday girl looked, and sounded, very pleased with a burger to cap off her night -- blame it on the shots. It wasn't Usher in Sin City, but Kim seemed alright with the change of plans.
