While no definitive reason has surfaced as to why iconic French Vogue Editor in Chief Carine Roitfeld resigned from her top spot late last week, Racked is claiming that she might have been fired.

According to sources contacted by the Web site, the top brass at French Vogue publisher Condé Nast has been disappointed by recent reports that Roitfeld overtly exchanges editorial attention to fashion labels for advertising dollars. In addition, her side gig as fashion consultant has ruffled some feathers at major fashion houses like Balenciaga, which banned her from its show after she allegedly allowed her client Max Mara to copy Balenciaga preview pieces.

In addition to other reports of shady play at French Vogue (read them in full over at Racked), the last straw supposedly came after giant advertiser LVMH, which owns Louis Vuitton, Céline, Givenchy, Fendi and others, complained to Condé Nast after seeing a spread in the most recent Tom Ford-edited French Vogue, featuring heavily made-up little girls posing like adults.

Racked also reports that the frontrunner for Roitfeld's vacant gig is Le Figaro Fashion Director Virginie Mouzat, who, um, might be regretting this nude self-portrait for racy Purple Magazine right about now.
