"I'll be showing soon", she said after lifting up her sweater to show her interviewer. But I'm married to Daniel. We're going to have a little human. "We can't wait to meet him or her. It's all such a mystery".
Earlier this month, Weisz hid her burgeoning bump under a flowing red gown and black cape as she attended the 2018 Night of Opportunity Gala in NY with her husband.
The pair, who began dating in 2011 and were married just six months later, are both parents already.
And 007 superstar Daniel has a 25-year-old daughter from his marriage to Fiona Loudon.
The actress personally confirmed the information to the press, noting that he and Daniel are very happy and looking forward to the birth of the baby.
Her pregnancy went unnoticed at the event, but it was clear to see that she and Daniel are very much in love.
The actress, a star of films such as The Lobster and My Cousin Rachel, revealed in a new interview with the New York Times that she is pregnant. Softer. I think we both felt very vulnerable and there was a real sweetness.
The mom-to-be told Evening Standard earlier this year that she "never thought" about getting married until she met hubby Craig.
Despite being bonafide movie star, Weisz says she's not totally at ease talking about her marriage, unlike other celebrities who open their relationship up to the public. "I really take my hat off to them".
She said: (Fleming) devoted an bad lot of time to writing this particular character, who is particularly male and relates in a particular way to women'.
