Despite her youth, she is a successful model, having been on the cover of Vogue Enfants, and used in numerous other fashion campaigns.
But this isn't a little girl modelling the latest in kidswear for high street stores; as the pictures reproduced in today's Daily Mail show, Thylane's shoots display a disturbing sexualised edge.
In one picture, the youngster is caked in make-up and leaning back against leopard print cushions wearing a ridiculously low cut top.
Others show her pouting into the lens lying on a fur rug, revealing a bare shoulder. The images appear in the current French Vogue, in an issue guest edited by designer Tom Ford.
Campaigners have expressed their outrage that a young child should be posing in such a way, with the Mother's Union telling the Mail Online they had 'grave concerns' about the agency who represent Thylane.
They said: 'Photo shoots requiring her, a 10-year-old-girl, to dress in full make-up, teetering heels and a dress with a cleavage cut to the waist across her pre-pubescent body deny Blondeau the right to be the child she is.
'These images would, we hope, post Bailey Review, not pass through the standards of magazines, on street advertising and other media within the UK.'
Thylane's parents are actress and TV presenter Véronika Loubry, and former French international football player Patrick Blondeau.
The current trend for super-young girls to be fronting campaigns and photo-shoots has recently seen 13-year-old actress Elle Fanning strutting her stuff for the Marc by Marc Jacobs autumn/winter campaign, and 14-year-old Hailee Steinfeld modelling for Miu Miu.
What do you think of these pictures?
