In a new video which he just posted on Instagram, he made a joke out of himself while admitting that "fighting is not cool", reported Ace Showbiz.
In the clip, the 22-year-old pop singer was in a car with his friend Micah Cravalho who showed him something on his cell phone.
Bieber asked Micah if he showed him a fighting video. When Micah said "no," Justin said, "Fighting is not cool." Micah replied, "I know. That's why you don't take on 6'5 guys," and Justin smiled to the camera.
