In case you didn't realize it based on the hoots and hollers of men around the country, Kylie Jenner is now 18 years old.
For her birthday on Monday, the reality star received a cake (below), an utterly insane present from Tyga and a bunch of well wishes from her family members.
Here's a look at what those famous loved ones have had to say in honor of the milestone:
Caitlyn Jenner: Happy birthday to my little angel @KylieJenner. Officially my last adult, my work is done. Love you, proud of you.
Kris Jenner: Happy Birthday to my little shining light in my heart and my life!!! 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.
Kim Kardashian: Happy Birthday to my fierce baby sister @kyliejenner. 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!
Khloe Kardashian: Happy birthday to one of my best friends and one of the great loves of my life @kyliejenner!!! I couldn't imagine life without you!!! You make my life better.
Kylie - who can now legally purchase tobacco and (gulp!) pose in Playboy - marked her 18th birthday this past Sunday with a blowout bash at The Nice Guy in West Hollywood.
