ABC should explains why they put the backing track

Christina Aguilera slaying wit her vocals as usual, when will the lessors

Listen to the crowd singing alone with Legend

Obviously. Legend doesn't need to lipsync.

I was really wondering why she lip synced. Yassss.

Now if this was called "Proof that Xtina lip synced" we'd be on the 4th page already.

So true, Christina's haters remains pressed

It's pretty standard of networks to do stuff like this for live performances to ensure top quality. It really was not necessary in this case though, I wonder why they added the backing track.

Why did ABC snub her like that, then?

This changes my perception on everything now tbh. Like how are we supposed to know what's lipped and what's not now?

It was pointless for ABC to dub over her vocals, her vocals sounded perfectly fine

Very nice, but I ain't too happy with the addition of a backing track when one was not necessary. .

Legend X nearly ALWAYS sings live, so this doesn't surprise me.

she looks so HOT and skinny!!

I heard her singing buried beneath the backing track

Knew something was up.

WTF she sounds AMAZING. Was the extra weight making her sound bad because she sounds so good. she hasnt sounded this good in years

She sounded great!! The voice is so full and it warms my heart how the crowd went along when she asked them to sing the "ooh ooh oh"

So true!

So much better than the one presented on ABC
