A FIGHT broke out at Zac Posen's New York Fashion Week show on Sunday, with a PR for the label being slapped across the face.

Just before the show was scheduled to start, fire marshals decided to cut 60 seats from the designer's venue - leaving many front row attendees with nowhere to sit.Posen's PR agency - HL Group - were left with the task of accommodating guests, including president of French publishing house Jalou Marie-José Susskind-Jalou and her two daughters - L'Officiel stylist Vanessa Bellugeon and Jalouse stylist Jennifer Eymere.According to WWD, Susskind-Jalou didn't have a seat and HL Group cofounder Lynn Tesoro tried to find one for her.Dissatisfied with the situation, the family left the venue and started screaming at Tesoro.The debacle culminated in Eymere slapping the PR across the face.

"I said:'Don't speak to my mum like this.You have to stop speaking to her like that.'I said:'Be careful, I am going to slap you,' and she kept doing it, and it just happened," said Eymere after the show."I am sorry, I know it's bad to do that.It was a small slap.It was not strong.I didn't hurt her - it was just to humiliate her.She humiliated my mum, and I humiliated her in front of her crew.Voilà.I just said at the end:'Now you know you don't fuck with French people.'"
