Arthur de Soultrait, a friend of Pippa Middleton, is coming to her defense after one of their friends, Romain Rabillard, aimed a gun at photographers last weekend.
Romain, Arthur, Pippa and one other individual are now subject to potential prosecution for the bizarre scandal, which shocked the French, US and UK media.
Although Kate Middleton's 28-year-old sister has yet to address the scandal, Soultrait was apologetic in a statement on Wednesday, in which he defended her.
He also said the gun wielded at celebrity news media was fake.
"Last Saturday I was in a car with Philippa Middleton, and we were being followed by the paparazzi," Soultrait explains of the late night/early-morning incident.
"The car was being driven by a friend of mine, whom Pippa had only met a few hours before," Soultrait, 30, said of Romain Rabillard, a 36-year-old attorney.
"As a joke, my friend brandished a toy pistol in their direction."
"Obviously Philippa had no idea that he had the pistol, or that he was going to do that, and told him to stop immediately. She did not find it funny."
