Kylie Jenner was living the high life when she partied on her private jet for her friend's birthday.
The makeup mogul, 23, and a group of pals jetted off on the luxury plane, worth around £72million, to celebrate Yris Palmer's big day over the weekend.
The group downed shots and cocktails and swigged on bottles of champagne as they documented their antics on Instagram.
Yris, 30, who is a YouTuber and also runs her own company, Star Lash Extenisons, cosied up in the spacious plane seat while dressed in a blue velour tracksuit.
She had two designer handbags in tow and sipped a drink as she relaxed during the flight.
Yris also sported a pair of Kylie-branded slippers and showed off her diva credentials by sporting her designer shades indoors.
Kylie had dressed comfortably for the flight in a baggy white jumper and a pair of matching jogging bottoms.
She looked in her element as the group clinked their glasses and downed shots together.
The group enjoyed a tray of six glasses of rose champagne to kickstart their flight off with a bang.
They also had fruity-looking tropical cocktails with slices of pineapple and little umbrellas in.
The gang appeared to be having a blast and posted multiple videos of themselves cheersing to the birthday girl with their drinks.
Kylie made sure Yris was lavished with attention during her birthday trip, shouting right before drinking hers: "To Yris!"
A tray of cupcakes with "Happy birthday Yris" spelled out with letters on each cake were also on offer.
Kylie had printed out a full itinerary for their girls trip, which started with a birthday dinner for Yris on the first night.
On the second day, they had a full list of activities planned, including a boat trip with rides on jet skis and snorkelling.
They also got massages and did wine and cheese tasting, which was followed by a slap-up dinner.
They were seen on a tropical island enjoying some birthday cake and some more wine and cocktails.
A special gazebo had been set up for the group so they could have their dinner right on the beach.
Kylie's daughter Stormi and Yris' daughter Ayla accompanied them on the trip, with the little girls enjoying some play time together.
They donned matching life jackets as they hung out on the lower deck of the boat the group had hired.
Yris and Kylie have been friends for around six years after they met when she did the Keeping Up with the Kardashians star's lashes.
The businesswoman has said she often turns to Kylie for advice about her company after the success of Kylie's firm, Kylie Cosmetics.
The duo have daughters close in age and they often spend time together while the girls have playdates.
