EXCLUSIVE: 9 Best Moments At Kylie Jenner's 18th Birthday Bash

The Kardashian and Jenner clan (Kendall, Khloe, Kim, Kanye, Kourtney, Caitlyn and Kris) filled up on dinner at The h.wood Group's The Nice Guy. But step-brother Rob Kardashian and Kourtney's ex Scott Disick were MIA for the big event.

Once the KUWTK birthday girl arrived at the Bootsy Bellows venue, she was greeted with all kinds of A-lister party-goers, like, EJ Johnson, Malika Haqq, Sean Ross, Skyler Shaye, Chuck Liddell, Sofia Richie, Hayley Baldwin, Quincy Combs, Kylie Massey, Nina Dobrev and Bella Hadid, to name some.

And just like any 18-year-old's party, young love was blossoming in the corners of the Bootsy Bellow room, among those being Joe Jonas and girlfriend Gigi Hadid who he is absolutely gaga over. "Joe couldn't take his eyes off of her or let her out of his sight. They are getting really serious and are falling hard for each other," dishes an insider to Star.

Even Kris Jenner hit up the party scene with Corey Gamble after dinner, which an insider says appeared the momager has one tight and short leash around her boyfriend's neck. "He does anything she wants and follows her around like a puppy. You can tell she loves the control," says the source.

Zayn Malik rolled in late to the party around midnight and made a beeline straight to Kylie's table to wish her a happy birthday in person. "He didn't really give anyone else much attention," a spy told Star, "He had one goal and that was to get to her table." Star readers know the former One Direction member just broke off his engagement to Perrie Edwards.

Music was supplied by none other than Kylie's boyfriend Tyga, and other musical artists Pia Mia and Rae Sremmurd. Plus, Tyga took every chance he got to call Kylie his "special girl" on stage over a handful of performances he did for her.

Moments after calling her "the most beautiful girl in the world," he announced there was a special surprise for her waiting outside. A diamond ring?

Not exactly—but almost as shiny! Tyga bought Kylie a $320,000 white Ferrari for her 18th birthday. "She was so stunned and put her hands over her face," an onlooker says. "She gave him a big hug and kiss and said, 'Are you serious? Thank you, baby!'"

At the end of the night, Kim, Khloe and Kourtney cut out of the venue first. But the birthday girl and sister Kendall didn't leave until 2 a.m when the party finally died down.
