Klein and Thyfault announced they were expecting their first child in March. The actor took to Twitter on his birthday to share the happy news.

Next to a photo of his beloved’s bare belly bump, Klein wrote, “My beautiful wife Laina and I are expecting our first child. 23 weeks along. Gratefully blessed on my 37th B-Day.”

The couple were married in an outdoor ceremony in August 2015 after a four-year courtship and December 2014 engagement.

Klein described their Montana nuptials as the “perfect day,” adding that he and his wife love nature and have families who enjoy traveling, so the location was perfect for them.

“Promising forever was definitely the highlight,” Klein, who has struggled with and overcome alcoholism in the past, told PEOPLE shortly following their wedding day. “Nothing gets better than that.”
