Kylie Jenner is celebrating her birthday in true superyacht style.
The 22-year-old businesswoman and reality TV star has chartered the 300ft (92m) megayacht TRANQUILITY for the occasion, and is spending her birthday week exploring Italy's Amalfi Coast region.
Now, Kylie is sharing the incredible experience of chartering a superyacht with her 143 million Instagram followers.
Birthday girl Kylie celebrated her 22nd with a glamorous party on the decks of superyacht TRANQUILITY.
All of her friends and family were involved, with videos of Scott Disick, Kris Jenner and Anastasia 'Stassie' Karanikolaou posted to social media.
The businesswoman, whose company 'Kylie Cosmetics' is estimated to be worth $900 million, posted a video to her Instagram Stories of her running down the corridor of the superyacht dressed in white.
Viewers are given a sneak peak into the interiors of the yacht, with its impressive glass elevator and intricate wall panelling.
Other videos offer a great look at the yacht's enormous tender garage, as well as TRANQUILTY's wide expanses of open deck, which have been dressed up in fairy lights for the birthday festivities.
The star was snapped posing on deck in front of a wreath of flowers spelling out '22'.
She also posted some pictures of yummy-looking cocktails being served, a breakfast spread of fresh fruit and pastries, and the corridors of the yacht filled up with yellow and white balloons.
Kylie has been loving the experience of renting superyacht TRANQUILITY, and she has posted several Instagram posts of herself making the most of her time on board.
The birthday girl uploaded a video of herself, boyfriend Travis and Corey Gamble jumping from the decks of TRANQUILITY. In the water, Seabobs and other toys are on hand for them to play with.
The star captioned the video 'Hell of a life' and Corey Gamble has commented, saying they jumped around 71ft from the decks.
Kylie has also been enjoying taking a break and unwinding in the Italian sun.
However, the 22-year-old is still working, as she poses alongside her new birthday makeup collection, which launched on her birthday.
As well as exploring Capri, Kylie also visited the Amalfi Coast, taking the time to step on shore in Nerano and Positano.
The star captioned a photo of daughter Stormi on her lap with 'Perfect day in Positano' and wrote 'blessed' on a picture of herself on a balcony posing with a Jacquemus bag.
Kylie's group have also been sharing their experiences on social media.
The entourage visited Le Sirenuse, a chic hotel and restaurant in Positano. With incredible views over the town, Kylie and her friends enjoyed aperitifs, nibbles and some selfie-taking.
Kylie is accompanied by plenty of family and friends, including rapper boyfriend Travis Scott and their one-year-old daughter Stormi Webster.
Her mom Kris Jenner and her beau Corey Gamble are also enjoying the crewed yacht charter vacation.
Scott Disick and his model girlfriend Sofia Richie are involved in the birthday celebrations too, as well as bestie Anastasia Karanikolaou and assistant Victoria Villarroell.
Yris Palmer and Tiffany Sorya have also joined in the celebrations.
As for the other Kardashian-Jenner sisters, it's believed that Kourtney might join the party later. She is currently having her own family yacht charter further up the coast of Italy, in Portofino.
Kendall, Khloe and Kim are not expected to attend their sister's 22nd birthday. It looks like former bestie Jordyn Woods also won't be attending the event.
Kris has already shared a birthday message for her youngest daughter on Instagram, captioning a post 'Morning Sunshine! #HappyBirthdayKylie #love.'
She also took to Instagram stories to share the birthday love. "It is the greatest joy and blessing to be your mommy and watch you grow into such a beautiful woman inside and out." Wrote Kris.
Kylie certainly kicked off her birthday bash the right way, with a video posted to her story showing the crew of TRANQUILITY singing her happy birthday with slammers and sparklers.
With an incredible selection of amenities and on-board facilities, TRANQUILITY is one of the most well-equipped yachts on the charter market.
She was the first yacht in the world to be built to Passenger Yacht Code Regulations, which means she can host up 22 people on board. On non-PYC yachts, the maximum limit is 12.
On-board highlights include an enormous beach club and wellness centre, which comprises a gym, massage room, sauna, Hamman and beauty room.
The motor yacht is also equipped with a circular swimming pool spanning 20 square metres and a certified helipad for arriving and departing with ease and flexibility.
This isn't the first time that TRANQUILITY has featured in the news.
Last year, it was alleged that the yacht, formerly known as EQUANIMITY, had been purchased with illegal funds in the 1MBD scandal.
She was sold by the Malaysian government earlier this year in an attempt to recover lost monies.
Megayacht TRANQUILITY costs approximately $1,249,500 to rent per week plus expenses.
This price doesn't include the cost of fuel, food or other expenses.
