The 27-year-old Age of Adaline star and her hubby welcomed their first child together in December, according to Page Six, which reported that Blake delivered the baby near the couple's home in Bedford, N.Y. just before the new year.
Although the baby arrived earlier than expected, Blake and her little one are both healthy and doing well, according to the mag. The baby's sex has not yet been revealed.
Back in October, Blake gushed about becoming a mom, telling Us Weekly, "It's something that I've always wanted ever since I was a little girl. I never knew what I wanted to do for a living but I knew I wanted to have a lot of kids because I had come from a big family, so it was always important to me. So it's just the excitement of that finally being here."
Ryan was also excited, telling People in November he was ready for everything that comes with being a dad.
"I don't have a weak stomach," he told the mag. "I'm good with diapers and diarrhea and all that kind of stuff because I have lots of nieces and nephews, so I've done it all before."
As far as what he was looking forward to the most, the Turbo star said, "I'm just excited about having a buddy. We don't know if it's a boy or a girl yet, but whatever it is, you have this tether to reality that never goes away."
Congrats to the couple!
