The actor shared the news in a touching Instagram post today—which also features him kissing Reed's adorable baby bump—where he gushed about his wife and their impending arrival.
"To our friends, family, and rest of the world. In my 38 years on this earth I've never experienced anything more powerful and beautiful than this," he wrote. "I can't think of anything more exciting than this next chapter and we wanted you to hear this from us first. This has been the most special time of our lives and we wanted to keep it between the three of us for as long as possible so we could enjoy this time with each other and our little one who is growing so fast...because that's what they do, they grow so fast. Thank you for your kind energy. Love, Ian."
The mother-to-be also shared the same image on her own account, which she captioned: "Hi Little One. I know you, but only because I feel you. How is it possible to love someone so much already? All I know for sure is it's the strongest feeling I've ever felt. We've been sharing this body for quite some time, and we've already experienced so much together. We can't wait to meet you... Love, Your parents."
The famous pair were married in April 2015, and have never been shy about showing their love for one another. Cheers again to the growing family—we wish them all the best.
