The twenty-two-year old appeared on the set of Allen's film, which is being shot in Barcelona, free of make-up, in an outfit that suited her role as a humble tourist.

But bad clothes aside, the face of L'Oreal still looked a million dollars.

The film, Scarlett's third with the infamous Oscar-winning director, will star Johansson, alongside Spanish beauty Penelope Cruz and heartthrob Javier Bardem. Allen has featured his favoured muse in films 'Scoop' and 'Matchpoint'.
