Not only is she stunning, but she's quite sneaky! Scarlett Johansson and Romain Dauriac had a super hush hush wedding on October 1, and after the New York Post first reported the story yesterday, Us Magazine confirmed with local county officials that the 30-year-old actress had tied the knot at The Ranch at Rock Creek in Philipsburg, Montana.

The Post reported that Johansson and Dauriac, who welcomed daughter Rose Dorothy in early September, had "a very intimate ceremony after the birth of their daughter" and that they "kept the wedding a big secret because they both wanted privacy."

Last night Johansson attended the Gotham Independent Film Awards in New York City, and she showed off her killer bod in a short black dress. Last month Johansson walked the red carpet at the 2nd Annual Champions of Rockaway Hurricane Sandy Benefit in NYC, and she was seen with a diamond-studded band under her engagement ring, which prompted media outlets to begin speculating that she had indeed tied the knot.

Congrats!
