Kendall Jenner has really gone above and beyond on behalf of one of her clients.
In order to promote Estée Lauder's new "knockout" mascara, Kendall gives us a masterclass in social media.
And this includes, if you can believe it, knocking herself on the head with her mobile phone in the name of not taking herself too seriously.
The video, which was posted by Estee Lauder a couple of days ago, is a wonderfully tongue-in-cheek look at what it takes to be a social media star.
As much as it seems to start in a serious vein, with Kendall confirming that the only way to become a celebrity these days, is to make your private life very public as the Kardashian family have done, it goes on to take a sweetly self-mocking tone.
She tells her viewers to "keep it real", while posing with a dazzlingly huge pair of fake eyelashes hanging off her otherwise petite face.
The final note is one of surprising comedy - as Kendall throws her phone in the air to take a "no hands selfie," resulting in a knock on the head as the phone lands on top of her.
