"Most of you probably have no idea that I'm married and have two amazing little boys (Calem 3yrs and Edan 1.5yrs.) But today, the strongest person I know, @catritchson gave birth to our newest addition, Amory Tristan Ritchson. Say hello!" he captioned a photo of his little bundle of joy.

The actor added, "He weighs in at a cool 7lbs 12ozs and is only allowed to be a football player or a rapper. Love you Amory. Say hi to a world in need of more joy, innocence and love, like you."

The birth comes just one week after Alan celebrated his own birthday, which Catherine commemorated with a sweet message on Instagram.

"Happy birthday to this fun-loving, imaginative, brilliant, courageous, artistic, powerful force of a human being," she wrote. "Words can't describe the gratitude I have for God placing you in my life more than 15 years ago."

Congrats to the new family-of-five!
