These are the years that define you, Kendall Jenner. And as her sister Kylie Jenner once quipped, the star of "The Kardashians" is no longer "like 30" as she officially celebrated her milestone birthday on November 3, surrounded by an intimate beachside bash with sisters Kim Kardashian, Khloe Kardashian, and Kylie, mom Kris Jenner, and pals such as Hailey Bieber and Justin Bieber. The model and around thirty of her loved ones savoring an al fresco meal at a long table under a beachside cabana, adorned with string lights and, of course, plenty of her 818 Tequila.

Kendall shared a glimpse of the festivities on Instagram on November 3, featuring a large balloon sign wishing her a happy birthday and dancing under a disco ball. Indeed, Kendall—clad in a silk wrap dress with an open midriff, brown bangles, and statement earrings—included a video in her round-up of her jamming out to Chris Brown's "Forever" by the dinner setup, before she ran over to a group of her pals enjoying the makeshift dance floor.
Naturally, Kendall's friends and family were emotional about her entrance into a new decade. "I can't believe you're thirty," Khloe, 41, wrote in a heartfelt Instagram post on November 3. "It feels impossible and yet, here you are; more radiant, grounded, and beautifully you than ever before." The Good American founder couldn't help but heap praise on her little sister. "You do what makes your heart happy, yet you still move through life with the most selfless, giving spirit," she continued. "That balance; living for your soul while still thinking of others, is something so rare and it's what makes you truly extraordinary."
Meanwhile, Kim used her birthday shoutout to manifest a powerful decade ahead for Kendall. "May this decade bring you the kind of love and joy you so freely give to everyone else," the 45-year-old wrote in her own Instagram post on November 3. "I love you more than you'll ever understand!"
Kylie also got sentimental about her sister's big day, sharing a supercut edit video of their sweetest Kardashian moments through the years on her Instagram Story, set to a mashup of "Last Kiss" by Taylor Swift and "I Love You, I'm Sorry" by Gracie Abrams. And while eldest Kourtney Kardashian couldn't make it to the bash, she expressed love for all of her sisters in a comment on Kim's post, writing, "FOMO miss u guys."
