The Lucy star reportedly married her fiancé Romain Dauriac in a top-secret ceremony Oct. 1 in Montana, according to E! Online, which reported that the wedding took place in Phillipsburg.
Scarlett and the French journalist's nuptials come just a month after they welcomed their first child together, daughter Rose, in September.
It shouldn't be too surprising that news of the 30-year-old actress's wedding is just surfacing, considering the couple never announced their engagement themselves. Instead, Scarlett popped up wearing a diamond sparkler on that finger when she walked the carpet at the premiere of her film Under the Skin at the Venice Film Festival in September 2013.
Scarlett revealed that she was pregnant in a similar fashion, opting to show off her small baby bump for the first time at the premiere of Captain America in March, rather than verbally confirming the news herself.
This is the second marriage for Scarlett, who split from Ryan Reynolds in 2010.
