The two recently welcomed a daughter and are excited to add the new baby to their blended family.
Both Hollywood A-Listers have children from previous relationships and have been married to each other since 2011.
Rachel shares an 11-year-old son, Henry, with director Darren Aronofsky. Daniel has a 25-year-old daughter named Ella with his ex-wife Fiona Loudon.
Rachel confirmed her pregnancy way back in April and she revealed her joy to E! News. The 48-year-old said, "We are ready. Very excited.”
The Favourite actress opened up to The New York Times that same month and expressed more excitement for her new little one. "Daniel and I are so happy. We're going to have a little human. We can't wait to meet him or her. It's all such a mystery."
