If you thought Kylie Jenner's yacht birthday looked fun, you haven't seen anything yet.
The billionaire shared some never-before-seen footage from her birthday week in Italy, and now we know just how wild Kylie and her friends got.
Booty, Booty, Booty:
The "Keeping Up With The Kardashians" star and her friends -- which included Scott Disick's girlfriend, Sofia Richie -- lived it up on their massive sea vessel.
She and her besties played loud music and twerked in their teeny, tiny bikinis for the camera.
The girls were clearly confident showing off their summer bodies because they basically lived in bikinis the entire trip.
Kylie's mom, Kris Jenner, may have to watch her back because the ladies flocked to her man, Corey Gamble.
The KarJenner matriarch's boyfriend is seen in the video surrounded by bikini-clad party guests, but Kendall and Sofia stole the show with their dance moves.
The birthday footage also reveals that Kylie Jenner received an over-the-top lavish gift from her mama.
Remember that yellow Birkin that the star was seen touting around during the vacation?
That came from Kris and has a price tag that could run over $25k.
Sure, they've been on elaborate vacations together this summer, but are Sofia and Kylie even closer than we think?
Lionel Richie's daughter called the reality star her "best friend" during a birthday shout-out on-camera.
"Kylie, you're 22 and you've always been one year cooler than me," Sofia said. "I love you! You're my best friend. I don't know what life would be like without you."
So In Love:
The birthday trip wasn't all wild dancing and barely-there bikinis.
Kylie's footage shows she snuck in some intimate quality time with her baby daddy, Travis Scott.
While Kylie's birthday was almost three weeks ago, we so appreciate the birthday tease!
