Sharing a selection of photo booth snaps from the party, held at the Hollywood hot spot Nice Guy, Kylie, 18, spread some birthday love to her big sis via Instagram, nicknaming her "Kendall pot pie" in the photo captions.
In one snap, the two sisters are seen crowding into a photo with a load of other party guests, Kylie's new hairdo taking center stage and her sister Kendall appearing to have her hair tied up in a bun on the top of her head.
In another photo, Kylie is seen making a mean-looking scowl while she poses alongside her pal Gigi Hadid. "My model friends," the reality TV star captioned the pic.
Pregnant big sister Kim also shared a photo booth snap from the party, which showed her puckering up and planting a kiss on husband Kanye West's cheek. Kim, who has her hair pulled back into a tight ponytail, is wearing a black sequin outfit, while West looks more casual in a plain black hoodie.
"Mom & dad turn up," the 35-year-old star captioned the photo.
Kendall Jenner turns 20 today, Tuesday, Nov. 3.
