Actually, Justin Bieber should not ever apologize---officially or unofficially---for what he said. 
stuffsickpeoplehavetoputupwith:
The Canadian-born Bieber never plans on becoming an American citizen. “You guys are evil,” he says with a laugh. “Canada’s the best country in the world. We go to the doctor and we don’t need to worry about paying him, but here, your whole life, you’re broke because of medical bills.” (emphasis mine)
No one should ever apologize for making a 100% truthful and intelligent observation.
this is old news, but i liked that he said this. i kind of wish more celebrities would talk about this.
