Um....I am really confused as to why he would waste this opportunity and not perform his current or upcoming single.

^ I think he should have performed 'Ridin' Solo', but I don't think anyone would want to hear a ballad like 'What If'.

Horrible vocal performance. He still hasn't topped his "Idol" performance yet, which was awesome.

I cant stand people Imitaing Michael Jackson they never do him justice

Not bad! His dancing is amazing!

Just when my ear drums were starting to recover from his American Idol performance

He sucks live.

he such a wannabe chris brown I cant get over it

Mr. Derulo gotta work on those live vocals. And where did he get those diamonds? Better send them back to GaGa before she finds out.

Since he a Madonna stan, I'm only going to say work on vocal.
