The Lucy actress, 30, attended IFP's 24th Gotham Independent Film Awards sponsored by Euphoria Calvin Klein in Manhattan with her husband by her side. French journalist Dauriac, 32, sat in the audience as his stunning wife took the stage at swanky NYC restaurant Cipriani to speak as a presenter to the awards show crowd.
Johansson kept Dauriac with her at Monday's event, an insider tells Us Weekly, introducing him to friends and colleagues as "my husband." The Avengers star also took the chance to gush about her new baby Rose, showing photos of her infant daughter to attendees on her phone.
"She looked really happy," a second source tells Us of Johansson's appearance at the event with her hubby.
The new Mrs. Dauriac stunned at the star-studded affair, showing off her toned legs in a black minidress. The festive number featured sheer sleeves and sequined scalloping. She wore her cropped blonde hair away from her face and drew attention to her eyes with a shimmering smoky eye.
The blissed-out couple wed in secret on Oct. 1, exchanging vows in Philipsburg, Mont., a clerk for Granite County previously confirmed to Us. Sources tell Us that the private ceremony took place at the area's luxury resort, The Ranch at Rock Creek.
The nuptials went down just weeks after Johansson and Dauriac welcomed their first child together. Daughter Rose Dorothy was born Sept. 4, 2014, one year after the couple got engaged.
