Scarlett Johansson and fiancé Romain Dauriac have welcomed their first child.  On Thursday the Avengers actress gave birth to a baby girl who the couple have named Rose.

The 29-year-old's spokesperson, Marcel Pariseau, told The Associated Press that mother and daughter are doing well.

Pariseau asked that media respect the new parents' privacy; both Johansson and Dauriac are advocated of the 'No Kids Policy', the effort from celebs to keep children out of the public eye.

Johansson and Dauriac, a former French journalist, announced their engagement last September.

Congrats to the new parents!
