I don't think Lauren messed up -- she was just doing the harmonies. Lol. I think it just sounded weird cause her mic was up so high and it should have been lower than the girls singing the main part.
I didn't know Ally did the belting after the bridge -- always thought that was Dinah!
Problem with this performance is only the chorus. They all were singing the chorus WITH the backing track, AND Lauren's mic was up too high. Not necessarily a "bad" performance though.
Best decision for single. Hope it does well. LOVE this song.
