Surprise! Scarlett Johansson is a married woman.

The Granite County Clerk in Philipsburg, Montana confirmed to Gossip Cop that the 30-year-old actress did indeed tie the knot with fiance Romain Dauriac on Oct. 1.

Page Six was the first to report on the couple's secret wedding, which took place less than a month after the pair welcomed their first child, daughter Rose, in September.

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

Despite reports, Johansson and French journalist Dauriac did not marry in their hometowns of New York City and Paris, but exchanged vows in Montana.

Wedding speculation surfaced after Johansson was spotted wearing a gold band on her ring finger last month. Dauriac has also been sporting a ring on that finger since October.

The pair, who began dating in 2012, got engaged in August 2013. This is the first marriage for Dauriac and the second for Johansson, who officially divorced her first husband Ryan Reynolds in 2011.
