Mark WahlbergMark Wahlberg has revealed the arrival of his daughter Ella four years ago helped him become a much more rounded and mature adult.

He said recently: “From the age of 15 on, I’ve thought I was a man but I didn’t really become a man until I had my little girl, which was the key ingredient to helping me become a well-rounded person.”

“I don’t have a problem with showing a sensitive side. I like to see guys kick ass when necessary and I’m still a guy’s guy, but when I had my little girl that kind of changed everything.”

He added that he’s very protective of his little girl and will use skills he developed for new film Shooter to scare would-be boyfriends when she gets older: “They sent me to sniper training [for the film], so I could be the daddy shining his rifle when she’s 16 and the guy shows up at the house.”

“I might have the movie playing in the background too.”
