Natalie Portman and her husband, Benjamin Millepied, have reportedly separated following rumours he had an affair.

A source told Us Weekly on Monday that the couple, who share two children, called it quits after 11 years of marriage, reports Page Six.

“After news of his affair came out, they’ve been trying to work on their marriage but are currently on the outs,” the insider claimed.

A rep for Portman did not immediately respond to Page Six’s request for comment.

Portman, 42, was spotted in Sydney last week without Millepied, 46, despite it being their wedding anniversary.

The Black Swan star’s 4-carat, Jamie Wolf-designed ring was also noticeably missing from her finger — just weeks after she was photographed looking upset while out with the dancer.

It comes two months after speculation about Millepied’s alleged dalliance with climate change activist Camille Étienne began to swirl.

French magazine Voici published images of Millepied and Étienne, 25, meeting up in his office. They were seen entering the building separately and then leaving 10 minutes apart almost two hours later.

The accompanying article claimed Portman had learned of her husband’s alleged infidelity several months prior.

At the time, Page Six reported that the couple were battling to save their marriage.

Sources told the publication that the duo initially separated last year but were able to work through their marital woes.

“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,” one insider dished.

The source added that Portman is an “incredibly private” person and “her biggest focus right now is protecting the kids,” referencing son Aleph, 12, and daughter Amalia, 6.

Étienne is the author of For an Ecological Uprising: Overcoming Our Collective Powerlessness and counts famed environmental activist Greta Thunberg as one of her pals.

Millepied, for his part, met Portman in 2009 on the set of her Oscar-winning film, Black Swan, for which he was the choreographer.

He got down on one knee in 2010, and they said “I do” in Big Sur, California, in 2012.
