Gigi Hadid, 19, is the new face of Maybelline New York
The full campaign will be released in October later this year, but Gigi gave fans a sneak peek of the images, as well as a behind-the-scenes peek at her photos on the computer.
"I'm so beyond honoured and excited (at a loss for words, really) to be the new face of @Maybelline!" she captioned the image.
"Thank you so much to my team at @imgmodels @luizmattos1906 for believing in me and helping make this happen, and to the whole #MaybellineNewYork team for being so welcoming; it's such a dream come true to be a part of this family."
Gigi has already bagged highly coveted modelling jobs from walking the Chanel runway to featuring in Pirelli's world-famous calendar, however she revealed that Maybelline was a particularly special brand for her.
Gigi shared the exciting news on her Instagram account
"In middle school, I wasn't allowed to wear make-up," she explained to Vogue. "I secretly bought Maybelline's SuperStay 24HR concealer at CVS. I thought it as the coolest thing in the world."
When it comes to beauty, Gigi, who has been modelling since she was ten years old, admitted that she loves to experiment with cosmetics.
"I pay attention to how every make-up artist does everything," she said. "You have to try different things to see what you like best."
