Kendall Jenner's Birthday Party: Insane Scene with Tons of Celebs

Kendall Jenner can draw a crowd, which she did in impressive fashion at The Nice Guy in WeHo for her 20th birthday bash.

Gigi Hadid was one of the first to show, which is appropriate because of her new bond with Kendall ... we've confirmed they'll both be on the runway for "Victoria's Secret Fashion Show."

Also present ... Kim and Kanye, Ruby Rose, Khloe and Kourtney, Kylie and Tyga, Drake, Miguel, Lil Za and Jaden Smith.

If you get to the end of the clip, you'll see Kendall's birthday cake about to be thrown in a dumpster.
