The image on the right shows Karen leaning on a police officer outside 10 Downing Street.
Karen is among a host of leading ladies photographed at London landmarks for the Government’s GREAT Britain campaign to boost tourism.
Also taking part in this promotional campaign is Harry Potter star Bonnie Wright, Oona Chaplin and Lily James from Downton Abbey.
The celebrities were given exclusive access to Westminster Abbey, the Foreign Office and Hyde Park Barracks for several photoshoots.
VisitBritain said: ‘This will remind people London is a great city for fashion and shopping’.
More photographs can be seen in October’s issue of Marie Claire’s magazine, which is out tomorrow.
