French gossip magazine Voici reported that Millepier, 45, a successful choreographer, had a brief love affair with a 25-year-old French environmental activist. "It was short and it was over," a source confirmed to People about Etienne, a close friend of environmental activist Greta Thunberg and a household name in her own right.
Despite reports that flooded gossip sites over the weekend about the infidelity discovered by Portman in March, a source close to the two said they were still together and were documented earlier this week.
