"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," a source previously revealed of Millepied's secret romance with a young climate activist named Camille Etienne — whom he met "through mutual friends" in "a cliquey group in the film community who favor art and creativity over big-budget box office bonanzas."
Millepied and Etienne clicked while working together on the movie Carmen, and they reportedly were even closer than Portman may think.
"There is a lot that Ben is leaving out," a second insider confessed. "Like how attracted he was to Camille. It may have started out as a friendship, but it grew into something more. She’s been humiliated like never before."
Portman and Millepied tied the knot in 2012 and share two children together: Son Aleph, 11, and daughter Amalia, 6.
"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 insider noted.
