Scarlett Johansson, Romain Dauriac reportedly wed in September

PORTLAND, Ore., Dec. 1 (UPI) -- Scarlett Johansson and Romain Dauriac reportedly wed in September.

The 30-year-old actress and 32-year-old journalist married in a secret ceremony shortly after the birth of their first child, daughter Rose Dorothy. A source told Page Six the wedding took place in the U.S., likely in a remote but scenic location.

"Scarlett and Romain were married in a very intimate ceremony after the birth of their daughter," the insider revealed. "They kept the wedding a big secret because they both wanted privacy."

Johansson and Dauriac have been together since 2012, and got engaged in September 2013. The actress was allegedly overheard to say she and her fiancé would marry in "four weeks" at a dinner party in July.

Johansson last appeared as the title character in Luc Besson film Lucy. The actress will reprise Black Widow in Avengers: Age of Ultron in 2015, and is also scheduled to voice Kaa in a live action adaptation of The Jungle Book for Disney.
