The '13 Hours: The Secret Soldiers of Benghazi' actor learns a lot about being a parent from his wife - who is expecting their second child - and loves seeing her with their 23-month-old daughter Hazel.

He said: "She is the best mom that I could ever imagine . When you become a mother, you show a whole new side of yourself - and for Emily, that happened immediately.

"The exact moment our daughter arrived, she turned into this unbelievably caring and loving mother and I learn from her about parenthood every day."

John is pleased his daughter has an "adorable" English accent like his wife, and admits she gets confused by some of his Americanisms.

He told Britain's HELLO! magazine: "She had a big shock before Christmas, because we watch 'Peppa Pig' in our house, who talks about Father Christmas, and then when I came along and called him Santa Claus instead and she realised I was talking about the same person, she got very confused - I think I blew her little brain.

"She's actually got a little bit of a British accent right now - she calls Emily 'Mummy' and says 'wah-tah' instead of 'water', which is just adorable to me."
