The "Captain America: The Winter Soldier" actress is said to have tied the knot with her French journalist fiancé Romain Dauriac in a secret ceremony following the birth of their daughter Rose in September.
A source told the New York Post newspaper's PageSix: "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 sparked rumors they had married last month when the 30-year-old beauty—who was previously wed to actor Ryan Reynolds—was spotted wearing a gold ring on her wedding finger.
Although Scarlett and Romain are yet to confirm whether they are now man and wife, it's reported they decided against holding the ceremony in his native Paris and instead married at a secret location in the United States.
Scarlett, who began dating Romain in 2012 and got engaged in 2013, previously revealed she didn't want to "rush" into tying the knot as she wanted to "enjoy and really savour" her engagement.
However, the "Lucy" star was reportedly overheard telling a pal at a Hamptons dinner party in June that she and her fiancé would be married "very soon".
