Kendall Jenner can be seen taking no prisoners when she mocks her little sister in a preview for the Keeping Up With The Kardashians finale.
The supermodel makes a sly dig at her sister's lips as she layers on lipstick from Kylie's own company and rocks a pink wig in impersonation of her sister.
Ridiculing Kylie's promos for her brand, the 24 year old smeared on the make-up on her teeth and face.
"Oh my god," she laughed, "It feels amazing on my skin. It feels so f*****g good!"
She soon had 22 year old Kylie on a video call, where the younger sister gasped at what Kendall had done.
"I'm Kylie," Kendall said.
"You look cute as Kylie," her sister came back.
Kendall was at a lunch with other members of her hugely famous family - who'd also decided to dress up.
Matriarch Kris turned up as Khloe, while Kourtney perfected her sister Kim's look.
A clip released on the show's Instagram page shows some family friction, as Kim tells Khloe that she can make her life easier with a makeover.
Naturally, Khloe doesn't take too well to the insult, but winds up branding Kendall - who's the tallest of the Kardashian-Jenner brood - a "f*****g gazelle."
The family's been the subject of scrutiny recently after a suspicious silence on the matter of Caitlyn Jenner heading into the Im A Celeb jungle.
Kim, though, hit out at claims from fans that they'd abandoned her - insisting that ITV had never reached out to them.
