Don't know. Actually, there doesn't seem to be a lot of information about her at all. I can't find any bios or interviews; I can't even find how old she is.
There was one piece published in belgian magazine le Vif Weekend on upcoming belgian models one year ago. They had been selected by their respective agencies (Dominique models for Fanny back then) as their promising models. Here's a rough translation:
Fanny François, 20 years old, 1.75m, 82/61/89
Origin: From a small village near Lièges
An agent spotted her when she was shopping in Brussel at the age of 15. "For some girls things start right off but for me it took more time. It's only been a year that I can make a living out of modeling." They mention she already shot for Swatch, Agent Provocateur, spanish Vogue, japonese Dazed & Confused and english Marie Claire.
She says she was in the final cast for a Chanel beauty product campaign but that they picked the other girl. They also say she lives in Paris with her boyfriend who is a model too and that she enjoys walks, drinks served on a terrace and farniente. No sport, "I'm too lazy but it would be good that I start." About the future: "why not walking shows but my bust size is too large... And later doing theater."
Her favorites brands: Valentino ("beautiful dresses"), Céline, Chloe, Balmain ("cool")...
