Actress Scarlett Johansson and her fiance Romain Dauriac have welcomed a daughter.

The 29-year-old actress and Dauriac have reportedly named their first child Rose, reports femalefirst.co.uk.

A representative for the couple said the mother and the little one are both doing well following the delivery, but they are seeking privacy and do not wish their daughter to grow up under the spotlight.

The pair, who started dating in 2012, sparked rumours they were expecting a child together in March this year, just three months after Johansson revealed that she was keen to start a family.
