Blake was accompanying her husband Ryan for the New York premiere of the Pokemon movie Detective Pikachu.
Blake and Ryan Reynolds, 42, are already the proud parents to their two daughters James, 4, and Inez, 2.
The actor recently spoke about his family life.
“Blake and I don’t do movies at the same time. If she is doing a movie in Thailand and I am doing a movie in Vancouver we would just never see each other. We operate as a unit, and that works really well for us,” he told PEOPLE.
“The kids stay with us, and the family stays together, and that is where home is. So if we are in Spain or Utah or New York, as long as we are together, we’re home.”
