The 39-year-old "Deadpool" star, who was youngest in his family with three elder brothers, said becoming a father to his little girl was a dream come true for him, reported People magazine.
"Having a daughter was a dream come true for me. I would have made a terrible king. I never admitted it out loud, to myself or my wife, but I really wanted a little girl. It's the best," Reynolds said.
The actor says he has been transformed into a completely doting father.
The couple are now expecting their second child.
