Steve Kazee is loving is newest role: fatherhood!

The Tony Award-winning actor took to Instagram on Sunday to share a heartwarming and special message to his baby boy, Callum Michael Rebel Kazee.

Steve's little one—whom he shares with fiancé Jenna Dewan—will soon hit a major milestone: he's going to turn 2-months-old in a few days.

So ahead of the special occasion, the 44-year-old star wrote something extra sweet for his nugget.

"I wish I'd done this ten years ago," Steve's post began, alongside an adorable pic of his baby boy. "How could I know... How could I know... That the answer was so easy."

"My beautiful boy. I hope you see this someday and know that your daddy loves you better than anything in this world and that, to him, you are the brightest light in this darkest hour," Steve's post continued. "You give me hope. You give me love. You give me everything."
