The young woman's acting coach, Daniele Dubreuil-Prevot, revealed Caro died on Nov. 17, at the age of 28, according to reports. She had just returned to France after doing a job in Tokyo.
While Dubreuil-Prevot, Caro's longtime teacher, said she didn't know the cause of death, she spoke of Caro's battle with anorexia, adding that her student – who said she suffered from the illness since she was 13 – "had been sick for a long time."
The model is known for her appearance in a fashion ad campaign by Italian photographer Oliviero Toscani in 2007. Caro's naked body was shown with her skeletal frame and facial bones protruding. The images were splashed in newspapers and on billboards with the headline "No Anorexia."
Earlier this year, she made an appearance on Jessica Simpson's show The Price of Beauty to discuss body image issues.
