And, surely, the 41-year-old has confidently stepped into the role of Superdad, as seven months before the arrival of their bundle of joy, he eagerly welcomed advice from the fellow dads that follow him on social media.

"Happy Father's Day ye dads out there," Henry wrote on Instagram in June. "Turns out I shall be joining your hallowed ranks soon!"

"Any tips??" he continued, revealing the nursery in the background. "And don't worry, pillows won't be in the crib when the wee one arrives, just glue and scapels so he or she can build Warhammer miniatures.”

But he didn’t just rely on the internet to inform his new parenting techniques. In fact, when the couple first announced their pregnancy, the Argylle actor revealed that his parents were his biggest inspiration for becoming a father, telling Access Hollywood, “Natalie and I are very, very excited.”

Even before he knew he was going to be suiting up to be a dad, Henry had a vision for how he planned to step up to the task.

"If I ever have kids one day, I want to be the dad who's running round after them," he told Men's Health U.K. in 2017. "And if I do have kids, even now, it's starting to get quite late. But I want to be a fit and healthy dad, not hobbling round like, 'OK, I'm just going to catch a breather.'"

While Henry and Natalie may be stepping into a new chapter of their relationship, keep reading to see where it all started.
