How does the "youngest self-made billionaire" celebrate her birthday? In style, that's how.

In the days before she turned 22, Kylie Jenner was joined by friends and family on a luxurious Italian getaway. The reality TV star/makeup mogul kicked off the festivities earlier this week aboard a charter yacht that reportedly costs $250 million. Kylie provided a glimpse of the 300-foot vessel via Instagram, where she shared photos of her birthday breakfast, a hallway filled with white and yellow balloons, her passive flower arrangement shaped in the numeral "22," and the new iced-out Kylie Cosmetics necklace she received from Travis Scott.

Kylie also shared a video of her and Travis' daughter, Stormi, singing "Happy Birthday." And, yes, it was as adorable as it sounds.

Though she's been celebrating throughout the week, Kylie officially turned 22 on Saturday. Her parents, Kris Jenner and Caitlyn Jenner, each shared a birthday message on social media, posting throwback photos of their youngest child.

"You are the most amazing daughter, sister, friend and mommy ... watching you with Stormi has been such a wonderful blessing," Kris wrote. "I am so proud of you... You are truly an old soul and such an inspiration to everyone. your creativity, generosity, and huge heart is truly remarkable! You are an angel girl and I love you more than you will ever know."

Travis also shared a series of photos of his longtime girlfriend, whom he refers to as "wifey." 

"Every day I watch u grow more into this amazing superhuman," he wrote on Instagram. "Every day is the best the day with u here. May God continue shine on you. Happy fcking Bday, love ya."

Kylie's big sister Kim, who is reportedly not in Italy, also shared a touching birthday tribute to her little sis.

"When I think about you I think of a wise old soul who makes amazing decisions that are always true to what you really believe," Kim wrote. "You have always been so strong and confident in doing what is in your heart and I admire and respect that [...] I wanted to post a unseen 'music video' you, Kendall, and I did back in the day but didn’t want to embarrass you too much lol. I love you."
