If i was on Justin Beiber’s PR team with the job of repairing his tarnished image i would first have him lay low for some time. During this time he would focus just on music. The PR team will take full control of his social networking sites so his image would be controlled and everything posted will project a better image for Bieber. Lastly, we will slowly start bringing Bieber out to to the public eye through charity and volunteer work.
This is just brief but tactics used by most publicists for their celebrity clients.
