Right? Why even bother with the vocal training/lessons, when all she's going to do lip sync the whole show? I don't understand the point.
Maybe not the whole show. She needs to be OK at least for the live BALLAD!
But she smokes like a chimney...she needs to quit it for a while. When she was in Buenos Aires for the tour, the hotel's employees say the girl smoked constantly
Not her sounding all accomplished for putting in part time job hours, sometimes. 
Bless her heart.
