"Beyond grateful for the prayers and for this ultimate blessing. We couldn't be more in love," Elizabeth, 34, captioned a sweet photo of the family bonding in the hospital.

The couple has yet to reveal their son's name, but did give daughter Harper some love on social media as well.

"Homeward bound and just a little excited. #insistedonwearingthisdressfortwodays," Elizabeth captioned a photo of the little girl wearing a white dress with the words "Big Sister" spelled out in light pink.

The couple, who tied the knot in 2010, announced the pregnancy last September with a pic of her growing baby bump before hitting the red carpet.

"Ready to start the #torontointernationalfilmfestival festivities… All three of us," Armie, 30, gushed.

The actor did admit he was a little bit nervous about welcoming another baby into the family before the birth.

"I'm a little less nervous," he told Entertainment Tonight. "You have a little more faith in the human mechanism. The only reason you're here and I'm here is because it works. We got through with one good baby, I think we can do it again."

He continued, "It's one of those things where if I am dreaming, I don't want anyone to pinch me."

However, there is no denying Armie loves being a dad.

"It's great. It's the best thing in the world," he said about fatherhood. "It's sort of a whole new perspective. I don't even want to sleep anymore. I don't want to miss a smile. It's the best. I love it."
