Gossip Girl star Blake spoke about her new bundle of joy while appearing on Live! With Kelly and Michael on Tuesday (21 April).
While Blake, 27, said James "looks like her daddy," she joked that she "wants a maternity test."
Talking about being a first-time parent, she added: "You see a balcony and you're like, 'Oh, my God! The hotel needs to demolish this balcony because my child can't go anywhere near it.' Everything is just so much more heightened. We're crying all the time for no reason."
She also joked that nowadays, Ryan "smells like poop"!
Blake appeared on the show to promote her new film, Age of Adaline. The actress welcomed James with Hollywood star Ryan in January, but they are yet to unveil their baby girl to the world.
Blake kept her pregnancy under wraps for seven months by covering her baby bump with baggy clothes. She only confirmed her pregnancy in October 2014 on her lifestyle website, Preserve, where she posted a picture of herself cradling her baby bump.
