Kim Kardashian has been enjoying a slumber party, but with a very a lavish twist.
The reality TV star, 41, celebrated her 'ride or die' friend's birthday on board a luxury private jet on Wednesday.
While most people struggle to get comfortable and battle for leg room when flying, Kim and pals Olivia Pierson and Natalie Halcro all stretched out on cosy looking beds as they flew home from their holiday together.
Dressed in matching pink outfits from Kim's SKIMS collection, the tanned trio all posed for snaps together as they celebrated Natalie's 34th birthday in the air.
"Pajama Party on the PJ for @nataliehalcro’s birthday!!!! Love you Nat! Def a member of the ride or die club," Kim captioned a collection of snaps shared with her 284 million Instagram followers.
"Def a member!!,” sister Khloé Kardashian agreed in the comments, going on to add: "This is the cutest!!!"
"Best Bday sleep over ever [red love heart emoji] Love you," birthday girl Natalie quipped to her pal on Wednesday.
The three friends appear to be returning from a sun-soaked holiday together.
In addition to sharing barely-there bikini snaps, Kim took to Instagram on Saturday night to post a late-night poolside snap of herself, Natalie and Olivia.
"Moon Manifestations," the mum-of-four captioned the aesthetically pleasing shot of the trio, with a full moon pulling focus in the background.
Olivia posted the same snap to her Instagram account, captioning them: "Girl chat & moon manifesting."
Kim's girly holiday comes as it's reported her romance with Pete Davidson has become more serious.
The reality TV icon and the Saturday Night Live comic struck up a romance towards the end of last year, after Kim filed for divorce from estranged husband Kanye West.
The Donda rapper hasn't taken the mother of his children moving on well - allegedly spreading rumours about funny man Pete and threatening to beat him up in a leaked snippet of a new song.
But according to a source close to Kim, Kanye's attempts to win her back are achieving the exact opposite.
"Kim truly wants Kanye to be at peace with their marriage being over and find happiness, whether it’s with Julia or someone else, so they can focus on raising their children together in a more positive way," they told Page Six.
"She is worried about how all of these things that are being played out so publicly on Kanye’s end will affect their kids in the future and feels that any issues should be resolved privately."
Another insider claimed Kanye's actions "in an effort to convince Kim to come back" are "actually bringing Pete and Kim closer together".
