Not only does Celine Dion have the voice of an angel – she's also an INCREDIBLE impressionist.
She showed off her amazing ability to take off the singing voices of some of the world's biggest stars on The Tonight Show Starring Jimmy Fallon.
The French-Canadian singer took part in Fallon's 'Wheel of Musical Impressions' and when it landed on Cher, Michael Jackson, Rihanna, Johnny Cash and Sia, she did not disappoint.
