"Well, you're surprised anyway, you know," he said. "I needed to wrap my head around it. For a while we didn't figure this one out, for a while."

As for the lessons he's learned from fatherhood that have prepared the star for his second child?

"I was not prepared for how much love I would have in me," he admitted. "So I'm a little worried, like how can I love something as much as I love my daughter? But everyone says your love just grows, so don't be afraid of that, so that's my only thing."

So sweet!
