Well we did know they were pretty tight lipped about their relationship -- but this comes as a surprise! Scarlett Johannson reportedly quietly married French journalist, Romain Dauriac, back in September.

September was a big month for the couple -- they also welcomed their daughter, Rose Dorothy, that month.

Johansson's rep has declined to comment.

A source told the New York Post, "They kept the wedding a big secret because they both wanted privacy." The source also added that the nuptials were held stateside.

News of their nuptials comes just after the actress was spotted earlier this month wearing what was speculated to be a wedding band at a fundraiser for Hurricane Sandy victims.

The duo became engaged in 2013. This is the Avengers star's second marriage. Previously, she was married to Ryan Reynolds.
