The couple are expecting their first child together, the actress, 48, told the New York Times while discussing her new movie, Disobedience.
“I’ll be showing soon,” she told the Times, adding, “Daniel and I are so happy.”
Continued Weisz, “We’re going to have a little human. We can’t wait to meet him or her. It’s all such a mystery.”
Weisz and Craig, 50, married in 2011, just six months after they began dating. Both have children from previous relationships:Weisz has an 11-year-old son, Henry Aronofsky, with director Darren Aronofsky, and Craig has a 25-year-old daughter, Ella Craig, with ex Fiona Loudon.
The star also opened up about the pair’s relationship to the Times, saying, “I’m very happy being married, very, very happy.” She mused of the couple’s reserved nature when it comes to their romance, “We’re just really crap at talking about our private lives.”
Earlier this year, Weisz told the Evening Standard that she “never thought” she’d get married before meeting Craig.
“It was not an ambition of mine. It was the opposite. I couldn’t relate to romantic comedies — marriage seems to be the whole point of them. Then it just happened, happily, at a more mature moment,” she said.
Further asked if she thought marriage had changed her, Weisz told the Evening Standard, “I mean, I wear a ring all the time. I wear my ring with pride. I’m taken.”
