In fact, the Gossip Girl star, who is the youngest of five children in her own blended family, is already looking forward to having more children.
"I do want to just enjoy this moment," she says. "But I also feel like my first child is going to be the oldest sibling to the next kid, and that may change with each and every year. I'm looking forward to how one baby influences the other, and to my family as a whole, to every single chapter."
And though Blake and Ryan, who have been married since 2012, have kept silent on their newborn's sex, Page Six is reporting that their first child is a baby girl.
ET has reached out to their reps for confirmation, but has received no response.
And if you believe a now deleted tweet from someone who claims to work at Westchester Medical Center where Blake reportedly gave birth, the couple has decided to name their new bundle of joy Violet.
"Congrats @blakelively #blakelively glad to have you and baby girl violet in our care," the tweet read.
Though whatever the baby name may be, one thing that is for sure is that Blake is unsurprisingly on cloud nine these days.
