Scarlett Johansson and her fiancé Romain Dauriac have taken the plunge: the parenthood plunge, that is! The couple welcomed their first baby, daughter Rose, today. In a statement released to Associated Press, Johansson’s publicist shared that both mom and daughter are doing well. Johansson’s next big project (beyond parenting, of course!) is Avengers: Age of Ultron, scheduled to hit theaters next May.
