Scarlett Johansson is officially a mom!

The 29-year-old actress and her fiance Romain Dauriac welcomed a baby girl named Rose, her rep told The Associated Press . This is the first child for the pair, who got engaged in September 2013.

Johansson's rep said mother and daughter are doing well and added that, as supporters of the No Kids Policy in Hollywood , the new parents are seeking privacy during this time.

Johansson kept mum about her pregnancy over the last few months, but did say that she hoped to find a balance between motherhood and her career while promoting "Captain America: The Winter Soldier" earlier this year. She told the Wall Street Journal : "It seems so stressful to not be able to spend time with your family because you're constantly chasing the tail of your own success. There must exist a world in which I can balance those things, be able to raise a family and still make a film a year, or work on my own, develop things, do theater. I want to be able to have it all ... Selfishly."

"I know that with that there will be some sacrifices," she continued. "I know that's the struggle with working mothers and successful careers. It happens."

Well, here's to Scarlett's new life as a working Hollywood mama.
