Natalie Portman and her ballet dancer husband Benjamin Millepied are reportedly fighting to keep their marriage together after she learned that he had an affair with a 25-year-old lady.

The couple, who got married in 2012, reportedly separated last year but overcame their relationship issues.

Now that he has admitted to cheating, their marriage has once more been shaken. The former main dancer of the New York City Ballet may have been hanging out with the gorgeous young climate activist Camille Étienne, according to recent photos from France.

And a source close to the couple tells Page Six, “They have not split and are trying to work things out. Ben is doing everything he can to get Natalie to forgive him. He loves her and their family.”

“She is incredibly private,” the source added. “Her biggest focus right now is protecting the kids.”

We hear it was an open secret on the set of Portman’s upcoming movie “May December,” which shot in November over the course of 23 days, that she and Millepied were having problems.

Additionally, there were rumors that the couple was still in trouble at the Cannes Film Festival premiere this month. While Millepied, 45, was unable to be seen, Portman, 41, was making promotional appearances in the city on the French Riviera.

Greta Thunberg’s friend and environmental activist Etienne has published the book “For an Ecological Uprising: Overcoming Our Collective Powerlessness” and produced a number of short environmental films. Vanity Fair in France reportedly listed her as one of the “50 French women who made 2020.”

Portman and Millepied met in 2009 on the set of her Oscar-winning ballet movie “Black Swan,” for which he did the choreography. He was in a long term relationship with fellow dancer Isabella Boylston. They got engaged in 2010 and married at Big Sur, California, in 2012.
