Is it normal that I'm a girl but I don't like Justin Bieber? I don't find him attractive tho, when he was on One Time MV I think he was pretty cool, but now idk unlike the other girls who is crazy about him what I'm saying is I don't really like him..

Girls need to stand by their own opinion and not blindly follow the majority.
Normal.
Does that answer your question?
He's not that pretty either. and he doesnt have frigging muscles.
I'm sure he's a nice person but he's not attractive to me, he's far too girly looking and his music is regurgitated pop candy floss crap that fuck knows how many other "artists" have created.
