The 39-year-old actor, who has James, 12, and Henry, 4, however, said being a father is also "incredibly complicated", reported E! Online.

"It's incredibly complicated, I find it, to be a father because I have no idea what I'm doing. I haven't read any books but I know that if I did they would just confound me even more."

"It can be a terrifying thing¿but also there's a great liberation in being a father, if I can speak from a point of self-interest for a second. Because for the first time in your life you are not the most important thing in your world.

For the first time in your life you really have an understanding of what it is to love unconditionally. And it's a pretty extraordinary gift," he said.
