The birthday girl's other parent, Kris, also penned a long, sweet message via Instagram on Monday.

"Happy Birthday to my little shining light in my heart and my life!!!" the momager, 59, wrote, alongside a snap of Kylie as a baby. "You are one of the kindest, most loving, generous, sweetest, smartest, most loyal, brightest, most giving, infectious, hard working, bravest, dearest, hilarious and messiest girls I know… you bring joy and love into the world each day, no matter what you are up against.

Kylie's big half-sisters Kim and Khloe were equally loving in their shout-outs. "Happy Birthday to my fierce baby sister @kyliejenner," Kim wrote, alongside a red carpet pic of the pair. "It's crazy to think that the baby of the family is an adult! You have always known exactly what u wanted and gone for it! I so admire that! I love you so much! #BAB."

The now officially legal reality star marked her 18th birthday this past Sunday, Aug. 9, with a blowout bash at The Nice Guy in West Hollywood. Jenner sported platinum blonde tresses and an eye-catching silver minidress for the occasion, which was attended by her famous family members including Kris, Caitlyn, Kim, Kanye West, Khloe, Kendall Jenner, newly single Kourtney, and more.

After the party, her boyfriend Tyga surprised Kylie at Bootsy Bellows with a ridiculously expensive gift — a white Ferrari 482 Italia, which retails for $320,000. “He was a very doting boyfriend,” an observer told Us Weekly at the time. “He was taking her photos for her, leading her around the bar. The family was really spoiling Kylie. You can tell she felt like a princess tonight.”
