It's true! Scarlett Johansson has married her baby daddy Romain Dauriac. A clerk at the Granite County Court confirms to Us Weekly that the Black Widow of Marvel Cinematic Universe did exchange wedding vows with her fiance on October 1 in Philipsburg, Mont.

The hush-hush ceremony was reportedly officiated by Richard J. Miller at the Ranch at Rock Creek. Their marriage came less than a month after 30-year-old ScarJo gave birth to her first child with Romain, a daughter named Rose Dorothy, in early September.

Back in early October, Romain already sparked a marriage rumor as he flashed a gold ring on the ring finger of his left hand. It was fueled by Scarlett's appearance at a charity event in New York City where she rocked a diamond-studded band below her engagement ring.

The newlyweds were seen attending the Gotham Independent Film Awards together in NYC on Monday, December 1, marking their first public appearance since the marriage rumor was confirmed. Scarlett was glowing in a lacy black dress, and her husband looked sharp in his tailored suit.

The "Lucy" actress announced her engagement to Romain in September 2013. She was previously married to Ryan Reynolds who is now expecting his first child with wife Blake Lively.
