They were unrecognizable and gave the subway commuters a show that they can share with smiles.
I love seeing these two human beings together, it is always full of laughter and it leaves me with immense admiration for the level of humbleness they seem to always have.
It is a short little video, but as Christina is singing, it is very hard to mistake her voice even though she is disguised. She has a voice you can recognize from worlds away.
Hope you enjoy the video.
