Probably the worst lip syncing I've ever seen! He was awful at it!

I'm not a hater and I understand the kid is only 16. Actually I blame his managers. It's embarrassing to see him perform (and I use that term loosely) on a show that celebrates raw "LIVE" talent.
If the contestants on the X Factor who get paid nothing can do it then surely a kid that gets paid millions should respect that same audience and sing live, after all isn't that what his marketing team are selling to all those young girls out there?

With all that jumping around I would forgive him for a few breathless moments in his vocals, but there was nothing. And grabbing his mouth mic every now and then does nothing but convince gullible people into believing "ooh he must be singing live" when in fact his mic is completely off. Otherwise why would Dermot put his mic up to JB's mouth in his immediate post song interview.

Now if you wanted to see true talent and a "LIVE" performance you only needed to stick around and watch the following act minutes later the amazing Nicole Scherzinger.
