Am I a Justin Bieber fan? No, I think that he is someone who uses his power for bad rather than good. I will say one thing about him though, he really seems to love his fans. There have been videos for years, since he started of him with his fans. He really take his time with them, so it seems at least. Of course there have been times where there were reports he spit on fans, called them whales, shit like that which makes you think.
Just watch the video and enjoy it because for this little girl her life is now complete in her eyes. She just sang with Justin Bieber, someone she clearly loves.
Do I think Bieber will make a big turn around with his attitude and make a comeback? No, but I do think he will always have fans if he treats them like this.
