Cannes Film Festival began in 1946 and in that time has seen old school movie stars like Brigitte Bardot through to modern day A-listers like Margot Robbie and Leonardo DiCaprio sweep across its famous red carpets.
Not even royalty could resist the allure of the glamorous festivities, with everyone from Princess Diana to Queen Rania of Jordan paying a visit to Cannes.
The Monegasque royal family in particular has strong ties to the event - and not just because they're locals. Grace Kelly famously met her future husband Prince Rainier of Monaco there in 1955. in the year's since, Kelly's children and grandchildren have also become regular fixtures at the event.
