I almost expected him to get boo'd. Instead, he got a LONG standing ovation. He stay winning!
And to the person who asked if it was autotuned: He didn't sing it live, he was just lip synching to the album track so there was no additional autotune like on SNL or GMA.
He had better add Beautiful People at the end! Promote that single boy! I think Beautiful People could be his next number one. They just need to get him to perform it on Idol.
The visuals on that mashup were amazing and of course the dancing is hot. He usually sings live so I'm okay with the lipsynching on a national TV show since I know he didn't wanna mess up and wanted to really perform the whole songs and not have to take breaks to regain his breath.
