Scarlett Johansson has given birth to her first child with her fiance Romain Dauriac.
A spokesman for the 29-year-old said the couple have named their baby girl Rose.
Marcel Pariseau said mother and daughter are doing well.
He added that the couple are seeking privacy and are supporters of the No Kids Policy, the celebrity effort to keep their children out of the public eye.
Johansson and Dauriac, a French former journalist, have been engaged since September 2013.
The star was previously married to Ryan Reynolds.
Johansson's recent credits include the films Lucy, Chef, and Captain America: The Winter Soldier.
