Laetitia Aynié attended the Émile Cohl art school, and studied Visual Communication in Paris. She has been active as a freelance artist since 2002, and works in several artistic disciplines, such as illustration, painting and sculpting. Besides book illustrations, she has made the drawings for the three books in the humour series about women, 'Les guides au féminin' by Jacky Goupil at Vents d'Ouest. Aynié and Goupil also cooperated on 'J'attends un enfant… ma femme aussi!' and 'Le mec idéal c'est (im)possible', books in the same tradition, but published by Jungle in 2014. In 2015, Jungle published 'Le journal d'Aurélie Laflamme', a series for girls in diary format, drawn by Aynié and written by Véronique Grisseaux.
