The traditional Jewish wedding was held Saturday evening in the Big Sur coastal resort, some 390 kilometers northwest of Los Angeles, according to the magazine.
Photos leaked on microblogging site Twitter showed a grinning Portman in a tea-length, A-line dress with a sheer overlay that covered her arms and shoulders, and a long veil, in keeping with Jewish custom.
The dress was designed by Rodarte, a label run by two of Portman’s longtime friends, and the company behind her purple Grecian-style Oscars gown in 2010.
Millepied wore a blue tuxedo, People reported.
The vegan meal — following the actress’s preferences — skipped the wedding cake and ended with French “macarons”: rich, typically meringue-based cookies.
The couple, who live in New York, met in 2009 while filming “Black Swan,” the ballet thriller for which Portman won an Academy Award.
Millepied choreographed the dance scenes and acted in the film.
Spokesmen for the star, most famous for her role as Queen Amidala in “Star Wars,” did not immediately respond when contacted by AFP.
