Kim Kardashian wasted no time in corralling her mom and stepdad for a selfie that she named after the movie "The Parent Trap." (There is no indication she will follow the movie's plot and try to get the couple back together, though.)
With all the Internet-breaking selfie action, let's not forget Kylie herself, who wore all white with delicate gold heels. In an Instagram photo published by Khloé, Kylie appears deep in thought before blowing out her candles.
She wasn't wishing for a $115,000 Mercedes... because boyfriend Tyga had just given her one as his gift. Kylie drove the cherry-red vehicle to the party.
Outside, as the group split up, Kris and Caitlyn shared a warm hug good-bye.

Over the weekend, Kylie rocked platinum blonde hair while continuing her birthday celebration at Bootsy Bellows, where she was gifted another car, a $320,000 white Ferrari, again by boyfriend Tyga.
Party guests included Kris, Caitlyn, Kim, Kourtney, Khloé, James Harden, Gigi Hadid, Joe Jonas, Zayn Malik, and Noah Cyrus.
Kylie's older sister Kendall also got the cameras flashing with her sexy, high-slitted dress.
