Scarlett Johansson flew back to New York City to give birth to her daughter.

The 29-year-old actress, who moved to Paris last year to live with her French fiancé, Romain Dauriac, 32, decided to return to her hometown in the US in the final stages of her pregnancy, as she wanted her mother, Melanie Sloan, to be by her side when she welcomed daughter Rose Dorothy into the world recently.

A source said: ''She knew she would feel more comfortable in the United States.''

The insider added: ''Scarlett's thrilled to have a girl. She doesn't want to let the baby out of her arms..''

The Golden Globe nominee, who will voice snake Kaa in the 2015 animated film 'The Jungle Book', is planning to return to work soon and her fiancé, who is an advertising executive, has assured her he will take care of their daughter and support her 100 percent.

The insider added to Us Weekly magazine: ''Romain is happy to take care of Rose while she's on set.''

The 'Vicky Cristina Barcelona' star, who was previously married to Ryan Reynolds, has kept a low profile during the last few months.

But the source said: ''She enjoyed pregnancy.''
