This strange event was aired during Celine Dion's stint on Le Banquier- which is apparently the Quebec derivative of the game show that loves boxes: Deal Or No Deal. I'm not sure why they were filming this moment- or following her into the loo- but it proves that Celine doesn't have to mime the belts (as some have suggested) to latest single, Loved Me Back To Life. She's clearly more than capable of hitting the notes.
The video ends with the Canadian Diva showing her funny side, telling a man heading to the restroom- which she'd just left- that he should use it quickly before she purchases it for its "amazing" sound. I can only imagine what "sound" he thought she was talking about! (...at least I think she was joking....)
