Well most of the artists are forewarned as well as trained by their agencies to handle cases like this. The bigger the agencies' power within the entertainment industry the more security and opportunities they can provide to their artist provided said artist also pays back with their talent to the agency. As glamorous the entertainment industry is, its true uglyness can only be seen through the perspective of an artist/talent/idol or whatever names u wanna call them. All we outsiders and fans can do is speculate. If you are a true fan u must learn that not everything is as it seems and to have absolute trust in the celebrities who totally deserve it. Though it seems slightly easy but for fans to implement this ideology is really difficult :)
In real life, the gossip mags would have added many outrageous details to their article leaving the idol's reputation utterly ruined for life because the majority of the fans would have felt betrayed and disgusted by their idol's ideal image being shattered in their hearts. They might then become anti-fans resulting in some ugly situations like cyber-bullying, stalking, public humiliation. There are endless possibilities of the deadly repurcussions faced by the idols all because of their crazy fans' obsessive ideal imaging and the media hawkeyeing every celebrity for the sake of their version of truth projection. It is so sad as well as disgusting that because of us the media/paparazzi have the upper hand in either making or breaking these people.
But sometimes it is necessary for the people to be exposed for who they really are if they have done something truly objectionable or hurt others physically, emotionally and psychologically.
