The 29-year-old Lucy star and her fiancé Romain Durlac welcomed a baby girl Thursday and named her Rose, according to ABC News.
Marcel Pariseau, a spokesman for the couple, said both Scarlett and the baby are doing fine, adding that the family is asking for privacy at this time.
This is the first child for Scarlett and the French former journalist, who have been engaged since September 2013. Weeks after news of her pregnancy first surfaced earlier this year, the 29-year-old actress flashed her teensy baby bump for the first time at the premiere of her film Captain America: The Winter Soldier in March.
Scarlett never confirmed the pregnancy herself, choosing instead to stay mum and show off her bump as she made her way around New York City this summer.
Congrats to the couple!
