There was no shortage of laughs on set when Kendall Jenner and Lily Donaldson united for their latest Fendi shoot. Playing around in wigs and blue robes, the models dressed up as one another for a playful snap shared by the Italian fashion house.
"Who's who?" read the photo's caption. "@kendalljenner and @lilymdonaldson backstage at the #Fendi campaign photo shoot."
Hair stylist Sam McKnight, who first shared the image, also referred to the ladies' fun on set writing: "Kendall Donaldson and Lily Jenner or is it @lilymdonaldson and @kendalljenner?"
Despite the near ten-year age gap between the two beauties, the pair got on like a house on fire.
"Day 1... J a couple Smurfs relaxing," London-born Lily wrote alongside an Instagram photo of the duo lying side-by-side and playing on their phones.
"Smurfin," she later added next a selfie of her and Kendall on the set of the Paris photoshoot.
There's no doubt that Kim Kardashian's half-sister Kendall is making waves in the fashion industry.
As well as working on high-profile campaigns with brands such as Calvin Klein, Chanel and Balmain, the 19-year-old has also won praise from style icon Victoria Beckham.
The former Spice Girl gave Kendall's style her seal of approval last week, complimenting festival look at Coachella.
"@KendallJenner looking great at @coachella in #VBAviators x vb www.victoriabeckham.com," she captioned a picture of the Keeping up with the Kardashians star posing playfully in a camouflage bomber jacket and pouting for the camera.
As well as hitting the runway at fashion weeks around the world, Kendall is now also working for cosmetics giant Estée Lauder.
Acknowledging how far she has come from being an aspiring youngster, Kendall revealed in a promotional video for the brand that she used to play with Estée Lauder products she found in her mum Kris Jenner's make-up collection.
"To think back to me as a young kid going through my mum's make-up drawer playing with Estée Lauder to now, I'm a part of this family," she said. "It's something that I didn't really expect to happen so quickly. It's so crazy."
