Celine Dion's usually schlock-y output and diva-like personality have long made her a bit of a punchline. But there is no denying the French-Canadian can flat out sing. During a show in Las Vegas last week, Dion covered Adele's signature song, 'Rolling in The Deep.' It's a difficult song to do, as Adele's booming voice is so hard to measure up to. Check out how Dion does.

Pretty impressive, huh? Who knew Dion could be so soulful? It's not the world's greatest recording, yet it still makes you stop what you are doing and take notice. Kind of like the first time you heard Adele sing it.

Listen to Adele's original below, and let us know which version you think is better.
