Justin Timberlake in particular has grown a lot over the years and he managed to climb out of the slight aura of negativity that surrounded his initial work and public image. According to many of his fans though, that was probably a well-deserved attitude back then.
Timberlake didn’t use to be much different from what Justin Bieber is now in some regards, although he was also quite aware of his public image and took a lot of effort to stabilize and improve it. And in the end, he came out quite successful.
He’s well-respected right now and many people look up to him, while Bieber’s image has been going further and further down. We don’t know where this story is going to end up, but Bieber might want to take a step back and reassess his situation, taking some hints from his colleague Justin Timberlake.
In the end though, they both seem happy with their lives one way or another, so we probably don’t have a place to say anything in this situation. For what it’s worth, Bieber also hasn’t been suffering too much in terms of losing his fans, so we doubt that he cares a lot that he’s being discussed in the media so negatively lately. Whether or not he’ll change his image at some point, we have no idea.
