The 19-year-old model was named as a new face for the historic brand back in November, and now her first video campaign has landed, in which she is tasked with showcasing Estée Lauder's new release of the Little Black Primer.
This being a a lash product - the primer can be worn alone, under mascara or over to 'amplify volume and length – there's a lot of brooding close ups of Kendall's eyes.
But the model also gets to show off what she's learned on the catwalk too, strutting towards the camera in black jeans and a vest.
'I've always been really into my eyelashes, so this is a fun product for me,' Kendall said of the Little Black Primer.
'While I usually love a lot of mascara, sometimes I don't want to wear too much makeup, but I still want a little definition.'
'It's cool that you can use [the primer] just for tinting and it doesn't look like you have too much makeup on.'
While we're not sure Kendall's sister Kim Kardashian will be a huge fan of the product, given how she's not the biggest fan of the natural make up look, we sure that Kendall's 18.1 million Instagram fans will be sure to try it out...
