The French journalist who smacked a fashion publicist at a Zac Posen show has been slapped herself, with a $1 million lawsuit. HL Group co-founder Lynn Tesoro’s suit says the incident happened at Avery Fisher Hall Sunday when she was set upon by Jalouse magazine editor Jennifer Eymere, her sister Vanessa Bellugeon and her mom, Jalou Publishing head Marie-Jose Susskind-Jalou. The trio was très offended when Tesoro wasn’t able to immediately find them seats for the show because fire marshals removed 60 coveted chairs. A witness tells Page Six: “Lynn Tesoro was trying to help the French women find a seat, explaining there were no seats available on the front row, but one of the ladies seemed very angry and was being really mean to her. Suddenly, one of the French women sharply slapped Lynn in the face and stormed off. Lynn seemed in shock, but she was very elegant about it and kept her composure. Nobody could believe it had a happened.” The suit doesn’t identify the slapper, but charges the trio with “assault, battery, intentional infliction of emotional distress, slander and/or libel.” In an interview with WWD, Eymere said she was the slapper. “I said, ‘Be careful, I am going to slap you,’ and she kept doing it,” Eymere recounted. “I didn’t hurt her. It was just to humiliate her. She humiliated my mom and I humiliated her in front of her crew. Voilà. I just said at the end, ‘Now you know you don’t f**k with French people.’” When Page Six reached Eymere yesterday about the incident, she said “I can’t comment, I don’t want to talk about it.” When asked about the lawsuit she added, “I don’t know about that.” A source said that after the slap, the mother and daughters left Posen’s show, meaning they missed the surprise appearance of Naomi Campbell, the ultimate model of anger management. Sources further tell Page Six that the French women have not been on any Fashion Week guest lists since the incident occurred.
