Comedienne Christina Bianco impersonates 19 different Divas while singing Total Eclipse of The Heart.
You'll see who she's singing like appear at the bottom of the screen if you can't hear them being called out to her. She does Adele, Christina, Alanis, Celine and so many more and it's awesome.
I liked her Celine Dion the best
