I wouldn't even give him one, having had the misfortune to have heard some of his output escaping from the bedroom of my 10 year old daughter (pretty much the exact target market I imagine).
But, that said, there is no denying he is popular. I posted a news story last night which reveals that Justin Bieber has overtaken Lady Gaga to have the most viewed YouTube video of all time with his 'Baby' song.
If you are not quite interested enough to click the link and read the full story, the Bieber video had been watched a staggering 247,991,181 at the time of writing, which was less than 12 hours ago.
