Joe Jonas has held Justin Bieber's father responsible for his son's brat behavior.
While talking to Scene magazine, the 24-year-old singer said that if the dad is a party animal, the behavior can be picked up pretty soon by kids, E! Online reported.
The former Jonas Brothers member continued saying that youngsters like Bieber are under a microscope and have trouble finding balance.
His connection with his family kept him at bay from trouble while growing up in the public eye, he added.
