The short sketch titled 'It's Miss Actually' follows the story of a woman - played by the 'Black Swan' actress - who ditches her husband at the altar.

The film is directed by 'A Most Wanted Man's Anton Corbijn, who spoke of the "heroic" and "inspiring" woman depicted in the film.

He said: "To me, this story gives her a chance to become a true character: multi-levelled, involved and heroic...

"The story of a singularly beautiful and inspiring woman taking the boldest of steps towards a future that is wholly hers."

Natalie - who has worked with the luxury brand since 2010 - later sheds her wedding attire for a black cocktail dress and climbs into a helicopter where she flies over the iconic sights of Paris.

Meanwhile, Natalie previously admitted that she was "honoured" to be the face of Dior.

She said: "I remember when I first met the team - the elegant simplicity of the environment, the grey and white Parisian dream.

"Dior is very chic and very modern - bold, elegant, Parisian. Being the face of Dior is a great honour. Every time the team asks me about a new project, I'm excited about it."
