The criticism lobbed at Justin Bieber by Marg Helgenberger came out of nowhere this weekend, and apparently came as a big surprise to Bieber himself.
Bieber seems to be pretty shocked that the CSI actress said he was a "brat" on the set, citing numerous examples of the youngster's behavior.
He finds it especially odd, since they never actually worked together.
Bieber never mentioned Marg by name in his Twitter-buttal.
Bieber just went on Twitter and said in response, "it's kinda lame when someone you met briefly and never worked with comments on you."
Still, he added, "I will continue to wish them luck and be kind."
"rumors are just that...rumors. In the end if you just be kind and be yourself people will know who you are. That goes for anyone i think."
Biebs also said, "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."
You tell 'em, JB. And u b the man ur fans luv 4 ever 2.
