Fanning, who is the youngest member of the 2019 jury at the festival, wore a cold-shoulder flower-emblazoned Prada gown – which boasted a strikingly small 50s-inspired corset.
She disclosed this on her instagram handle,@ellefanning:
“Oops, had a fainting spell tonight in my 1950’s Prada prom dress but it’s all good.” She posted a selfie adding the hashtags #dresstootight and #timeofthemonth.

Fanning is one of nine film industry luminaries judging this year’s selection at the world’s top film festival.
They will announce who has won the coveted Palme d’Or for best film on Saturday, choosing one of 21 contenders. (NAN)
