Bieber just went to his Twitter page and without mentioning Marg by name ... said, "it's kinda lame when someone you met briefly and never worked with comments on you. I will continue to wish them luck and be kind."
As we previously reported, Marg went on a French radio show and said JB was "kind of a brat" when he guest starred on the show earlier this year.
Bieber added, "I know who i am and sometimes people r just going 2 say what they want. Keep ur head up and be the man ur mama raised. "
