Weisz, 41, who has a 5-year-old son Henry from her previous relationship with Black Swan director Darren Aronofsky, tells Lucky magazine that it’s not out of the question.
“Oh, I wouldn’t make one just for the sake of giving my son a sibling,” she says. “But you never know.”
Weisz and Craig, 43, who had known each other casually for years, secretly married in June in a small ceremony in upstate New York, having become close while filming Dream House together.
The James Bond actor has blue eyes – which might also influence Weisz’s decision about kids. Of children’s fashions, she tells Lucky: “There’s nothing like a blue-eyed boy in a stripy blue shirt.”
