The Entire Kardashian-Jenner Clan Turned 21 at Kylie's Birthday Party

The Kardashian-Jenner clan is known for their over-the-top celebrations, and Kylie's 21st birthday party may have been the biggest blowout yet. Last night, Kim, Khloé, Kourtney, Kendall, Kylie, Kris, Scott Disick, Kanye West, Caitlyn Jenner, Travis Scott, French Montana, Dave Chapelle, Nicki Minaj, Corey Gamble, and countless others gathered at Delilah in Los Angeles to celebrate the youngest sister's 21st birthday at what appeared to be a loosely themed Barbie party.

The Kardashian-Jenner sisters all donned micro-mini, '80s-esque party dresses in brightly colored hues, with Kylie and Kim opting for bright pink dresses and Kourtney choosing a shimmery purple number. The entire party was cast in a bright Barbie-pink light, including pink Solo cups emblazoned with "Kylie's 21st birthday," an all-pink ball pit complete with heart-shaped inflatables, and a pink balloon ceiling. Kylie even posted a photo of two disheveled Barbie dolls at 3 a.m. PST.

In addition to abiding by the same dress code, Kim, Khloé, Kourtney, Kendall, and Kylie pretended they were all turning 21 for the evening. In a show of support for their youngest sister, all five captioned multiple Instagram photos and tweets with sentiments along the lines of, "we're 21 today," "it's our 21st birthday," and, in Kourtney's case, "thank you for all of my birthday wishes" (her birthday is in April).
