Filming the 2010 ballet thriller "Black Swan" changed Portman's life in monumental ways. Not only did she win her first and only Oscar for her role as dancer Nina Sayers, but she also met her future husband while working on the Darren Aronofsky movie, which filmed from late 2009 to 2010.

Millepied was a principal dancer in the New York City Ballet from 2002 to 2011 and choreographed the film. He also played the role of David/The Prince.

In a 2018 interview with Hoda Kotb for Sirius XM, Portman said she was in "dreamland" while filming the physically demanding drama because she was getting to know Millepied at the same time. She called the early stages of their relationship "romantic" because they were catching feelings for each other while he was teaching her how to dance.

Portman denied any instant feelings for Millepied when pressed by Kotb, but called their connection "beautiful."

According to The Guardian and other unconfirmed reports, Millepied was living with his former partner, ballet dancer Isabella Boylston, in 2009 and eventually left her for Portman.
