The gun may be fake, but the bad news for Pippa is that French detectives are indeed examining the photographs which show her being driven through Paris by a friend as he brandishes a toy pistol.
Prince William's sister-in-law was in an Audi convertible, seated next to the as-yet unidentified driver who was pointing what seemed to be a pistol at the photographer.
Vicomte de Soultrait, whose party Pippa had been attending, can be seen in the back of the vehicle sporting a blue baseball cap while Miss Middleton, wearing a pair of dark glasses, is in the front, laughing as her friend points the gun.
A police source told the Press Association: "We saw the pictures on the internet and we expect to receive more information on the subject. We are looking into it."
If French authorities consider there is sufficient evidence for a prosecution, Miss Middleton and Mr de Soultrait could both be summoned to give evidence.
The 28-year-old sister of the Duchess of Cambridge was driven to the Gare du Nord station to board a Eurostar train to London on Saturday when the photos were taken. She has been holed up at her parents house in the countryside today.
Sixty years and hardly a slip.
