If he does that to a fan then is really shocking and I am disappointed in him. I had seen him in his debut days and he has good character and good upbringing. He respected women and in one occasion he even stand up for them when one of his female fans got pushed by a guy. He told off the guy sternly for pushing the lady. Well I guess ppl can change. Or he had let alcohol or maybe drugs taking control over him? But I hope he is not the celebrity that was mentioned
