It's not often that Hollywood celebrities make a personal appearance on the great British high street but then Scarlett Johansson has always been an exception to the rule. In this video she brings one of London's largest shopping Meccas, Oxford Street, to a complete standstill.

Since she became the face of Dolce & Gabbana's first luxurious make-up collection earlier this year the products have flown off the shelves. This summer their second collaboration with the smouldering actress is finally here, and what better way to bring the new range to life than by getting Scarlett to show it off in London in front of her adoring fans?

Discover how Scarlett wows the crowds in Selfridges, talks about the new Dolce & Gabbana range and generally just looks beautiful. All hail, Scarlett!
