Natalie Portman 's husband Benjamin Millepied allegedly had an affair with a much younger woman.
The French ballet dancer and choreographer, 45, reportedly had an affair with Camille Étienne, 25.
He is now thought to be "doing all he can" to try and save his relationship with his wife Natalie, 41.
But who is the woman who reportedly came between A-list actress Natalie and her French husband?
Camille Étienne is an environmentalist activist fighting for social justice and issues around climate change according to her Instagram page that has nearly 300,000 followers.
She has made several short films and documentaries and often appears on national TV in France standing up for her beliefs.
In November 2022 she shared an appearance from chat show Ce Soir and said: "Politicians who want to deny us this right want to maintain the status quo and prevent any world transformation. We will not have it."
She released her first book titled For an Ecological Uprising: Overcoming Our Collective Powerlessness last month.
The book discusses ways young people can get involved to stop climate change.
She has also teamed up with fellow eco-warriors including Greta Thunberg, Adélaïde Charlier, and Anuna de Wever in the past.
A source has said the affair is now over and the couple are still together while trying to overcome their marital problems.
"It was short-lived and it is over. He knows he made an enormous mistake and he is doing all he can to get Natalie to forgive him and keep their family together.
"Natalie is incredibly private and has no intention of playing this out in the media. Her biggest priority is protecting her children and their privacy," the source told People.
Natalie and Benjamin share two children together - 11-year-old son Aleph and six-year-old daughter Amalia.
Reports suggest Natalie and Benjamin’s marriage has been on the rocks since November last year.
However, just days before news broke of the alleged affair, the couple packed on the PDA as they made a trip to Cannes Film Festival.
Natalie and Benjamin dined with pals at the restaurant Georges and even shared a romantic kiss, as Natalie appeared to hold on to a red rose.
The Mirror has contacted Portman and Millepied's representatives for comment.
