Celebrity single mum Angelina Jolie fears her three-year-old adopted son has a violent streak because he's a good swordsman and knows how to fell a man.

The actress admits she was both horrified and delighted when little MADDOX knocked a security guard out by punching him in the genitals.

She explains, "There was this security guy that I'm close to and we're friends with him and he was playing with him and he punched him right in the nuts and pretty much flattened him.

"He was just playing. I said, 'Not good, not good,' then secretly went 'Good shot.'"

But it's little Maddox fencing skills that really impress mum: "He's really good. He's a tough kid."
