Scarlett Johansson and Romain Dauriac are officially married.

In fact, they have been for two months. The couple said "I do" in a secret ceremony on Oct. 1, which PEOPLE reports took place in Philipsburg, Montana.

According to Page Six, a source said, "Scarlett and Romain were married in a very intimate ceremony after the birth of their daughter. They kept the wedding a big secret because they both wanted privacy."

The couple has indeed been very private about their relationship and family life. They welcomed their first child, daughter Rose Dorothy in September. Johansson and Dauriac are supporters of the No Kids Policy and have asked reporters to refrain from taking photos of their baby girl in order to keep her out of the public eye.

It was revealed in September 2013 that the couple was engaged. However, the "Her" actress and her French husband avoided disclosing any details about the nuptials.

In March, Johansson told Wall Street Journal Magazine that she hopes to find a balance between her acting career and personal life, which she intends to keep separate.  

"There must exist a world in which I can balance those things, be able to raise a family and still make a film a year, or work on my own, develop things, do theater," said the 30-year-old actress. "I want to be able to have it all."

Johansson was previously married to "Green Lantern" star Ryan Reynolds. The actors divorced in 2011 after almost three years of marriage, claiming that their busy schedules took a toll on their relationship.

Reynolds is now expecting his first child with his current wife Blake Lively.
