Pippa Middleton Pictures in Paris During Gun Incident

Pippa Middleton left London to link up with friends in Paris over the weekend. She spent time Saturday and yesterday afternoon with her friends, brothers Marcy and Arthur de Soultrait, and on Saturday night, dressed up in a costume to attend Antoine de Tavernost's 29th birthday party. Antoine, the son of a French media mogul, hosted the Louis XIV and Marie Antoinette-themed bash that Pippa ended up leaving at 6 a.m.

She donned a period costume for a bash on Saturday night, but yesterday, during a car ride with the Soultraits and another pal, things got a bit weird — the third friend of Pippa pulled a gun on photographers. According to French law, publicly displaying a weapon — even if it's fake — is illegal, and the driver could face up to seven years in prison for the stunt. Even Pippa could be called before French police to testify in the case, and if found to have been complicit in the incident, could encounter jail time herself. Pippa and the Soultraits are mortified over the incident, according to reports.
