Justin sucks so bad
rebecca black duh friday is the most annoying song ever and i love justin bieber
omg nice question. i say BOTH
I can't stand either of them, but Rebecca Black would probably be worse in my opinion...
Justin beiber all the way!!!
Both, they are both annoying and have annoying songs
The most hated is probably Rebecca Black
But in my personal opinion Beaver sucks!
Justin and rebecca. I HATE both
Uhhhhm, the obvious answer here is Rebecca Black!!!! I heart Justin with all my heart he's kind,can sing,dress, he's auh-mazingggg!!!! But my guilty pleasure is listening to "Friday".
