Elle Fanning faints during Cannes dinner party

American actor Elle Fanning had a health scare when she fainted at the Chopard Trophee dinner party. While the news of her passing out quickly went viral, the dinner attendee said it happened so fast that people at the party barely even noticed it. "Most people in the room didn't even notice until after there was a brief pause, during which word quickly spread through the venue about what happened," the eyewitness revealed. The 'Maleficent' actor later confirmed on Instagram that she did indeed faint, but also asserted that there is nothing to worry about. She also shared her picture with a caption that read, "Oops, had a fainting spell tonight in my 1950's Prada prom dress but it's all good." She also added hashtags "dress too tight" and "time of the month," for further context. According to Variety, the actor's elder sister Dakota Fanning and British star Colin Firth quickly helped Fanning when she was falling off her chair. The 21-year-old star was then rushed away by Dakota and their team of security guards, after which she apparently slipped into a pair of comfortable PJs.
