JenniferConnelly and Paul Bettany are expecting their second child together.
The 40-year-old actress - who already has children Stellan, seven, with the English actor and Kai, 13, from a previous relationship with David Dugan - has confirmed her pregnancy just weeks after the pair appeared on the red carpet for the New York premiere of Paul`s new movie `The Tourist`.
Jennifer has previously highlighted the importance of being a mother, and said it made her change her life.
She said: "Becoming a mother has made all the difference in terms of learning to take responsibility for myself and my life.
"Parenthood changed the way I do everything. The biggest thing for me is wanting my kids to grow up safely and have happy lives. For me, that`s enough."
She also revealed she is not shy of her children swearing and is not a strict mother.
She said: "Things like bedtimes and cursing don`t bother me. I`m not offended if Kai is laughing and says something like, `That was f**king hard.` Or if I drop something and say `S**t`.
"But I make it clear that other people might find it offensive. And I won`t stand for cursing at someone or rudeness. I am quite strict about manners."
Jennifer and Paul met on the set of 2001 movie `A Beautiful Mind` and married on January 1 2003.
