Teenage sensation Justin Bieber performing U Smile and Baby Live on American Idol. ENJOY

I didn't like it. The performance felt blah.

I feel he can become a back-up drummer after the whole singing thing goes away

He was more entertaining than that other guy they had on.

Great performance

u smile = waste of time promoting.

LOOOOOOOOOOOOL No one noticed he is pulling an ASHLEE SIMPSON!

When I was watching it I was impressed on his vocal not until "Baby"... He was lip syncing!

I've noticed that he lips a lot of performances. When he did "The Tonight Show," he did it as well. He's not even good at trying to hide it.
