A certain time of the month and a tight dress do not a good combination make, as Elle Fanning apparently learned Monday. The 21-year-old actress and youngest juror in the history of the Cannes Film Festival fainted Monday at the Chopard Trophee dinner, where actors Francois Civil and Florence Pugh were honored. Civil had just been introduced on stage when Fanning fell out of her chair, Variety reports.
The ceremony was paused as Dakota Fanning helped her sister to her feet—Colin Firth reportedly offered assistance, too—before security escorted the pair out of the room. "Oops, had a fainting spell tonight in my 1950's Prada prom dress but it's all good!! #dresstootight #timeofthemonth," the actress later tweeted alongside a thumbs-up selfie. Spotted at an event Tuesday, Fanning will help decide the highest prize, the Palme d'Or, before the 12-day festival wraps on Saturday, per the AP. (Read more Cannes Film Festival stories.)
