Natalie Portman and Benjamin Millepied "marry in secret"
The couple - who are parents to 1-year-old Aleph - tied the knot in a secret Jewish ceremony at a home near Big Sur, Us Weekly reports.
It was recently revealed that Black Swan actress Natalie, 31, would wed Benjamin, 35, in the cliffside California coastal town because it's special to her.
A friend said: "Natalie and Ben will marry in Big Sur. It's one of Natalie's favourite places - whenever she needs a break from LA she goes there.
"This wedding is for their closest friends and family. It will be a very relaxed affair. They're not sending out invites. Natalie may not even buy a new dress!"
Natalie met Benjamin on the set of Black Swan in 2009 and the couple got engaged the following year.
The actress paid tribute to Benjamin when picking up her Oscar for Best Actress in the ballet drama movie last year.
She said: "My beautiful love, Benjamin, who has now given me my most important role of my life.
"Most importantly, my family, my friends, and my love, thank you so much."
