Idol controversy?

Looks like former AI contestant Justin Guarini from season one isn't really happy about this season's group performances. Justin is the co-host of idol wrap on the tv guide network. Then justin told everyone that the contestants is lip synching due to group's performance. Wow! so AI is a fake show?? So many denials! A rep for fremantle media north america westphal said, "the idols don't lip-sync. Period." well, not long after that, westphal confess to the media that, "due to extensive choreography and to balance their voices with open mikes against a screaming audience, the Idols to sing along to their own precorded vocal track during the group performances only." whuuut da heck is goin on in here? Some of the performances weren't live?? Ohh i hate it! I'm exactly agree with justin! Suck it idols!
