Bieber Can SING!!!

I can't believe he didn't lip sync. He does have my respect for getting into the music industry, but now he has my respect for actually performing LIVE VERY WELL! It's so weird............ o_o

BUT PLEASE! He might of heard Carly's version of the X Factor and thought, "Oh please. This is my song and you can't own it!"
Here's carly's version! COMPARE! 'Justin Vs. Carly'.
