Kendall Jenner Turned 21 and Kim Kardashian Wasn't Going to Miss It for the World

Try keeping up with this news: Kendall Jenner can officially party legally. The now 21-year-old model and Keeping Up with the Kardashians sister painted the town red (or, silver) in a sparkly little dress on Tuesday in Los Angeles in honor of the big occasion. Even Kim Kardashian stepped out to celebrate the milestone. According to Us Weekly, Kim was among the guests who attended the party held at Catch in L.A. “Kim was there in a sweater, in a great mood, and gushing to everyone about how amazing [husband] Kanye West’s [Saint Pablo] show is and how she loves going to his concerts,” the source shared. “She seemed in totally great spirits, very social and smiling with everyone.”

While other guests were photographed at the party — like Hailey Baldwin and Kylie Jenner — Kim remained out of any selfies. The insider added, “Kim gave Kendall an expensive piece of jewelry and a card."

What we're most floored by isn't Kim's appearance (which has become less frequent since she was robbed in Paris last month), but by Kendall's incredibly glam party garb.

However, little sis, Kylie, was definitely giving her a run for her money in the sexy style department.
