Watch Celine Dion Slay Adele's Hit 'Hello'

By
Celine Dion gave her fans quite the New Year’s treat.
While performing a special New Year’s Eve show at Caesar’s Palace in Las Vegas Thursday, the 47-year-old music legend covered Adele’s hit, “Hello.”
"If I may, I would like Adele to be part of our New Year's Eve," Dion told the crowd as they bursted into screams. "Don’t panic, she's not in the building. …Do we need to change the battery in my microphone? It kind of lost it a bit. Adele, hello? Hello?"
Dion then proceeded to give us all the feels, as you can see:
The amazing performance just adds to her fantastic return to Sin City. The “My Heart Will Go On” singer started performing again in August after taking a year-long break to take care of her 73-year-old husband, René Angélil, who is battling throat cancer.
ET caught up with Dion just as she was ending her hiatus, and she revealed that it was her husband who really pushed her to take the stage again.
“We don't know what the future holds," she admitted to ET, adding that her husband told her to be "back, strong, [to] do it, still share your passion."
