The 33-year-old star says her family is the most important thing in her life right now.
"The kids are my priority, so it's possible that from now on I will make fewer movies. I may even stop altogether," she told Italian Vanity Fair.
"I no longer have the ambition I had in my 20s."
"Usually people fall in love and everything revolves around the ritual of marriage, children are an afterthought … we did everything backwards."
"But sooner or later it will be the kids who ask us [to get married]. You know, they see films and start asking questions, such as, 'Why are Shrek and Fiona married and you're not?'"
