Celine Dion loves Ariana Grande's flawless impressions just as much as the rest of us!
The 22-year-old singer broke out some of her best impressions on Saturday Night Live over the weekend, including Dion, Britney Spears, Shakira, Whitney Houston, and more. In an interview on New York's Z100 Elvis Duran and the Morning Show on Tuesday, Grande hilariously revealed how Dion reacted to her take on that iconic voice.
Affecting Dion's French Canadian accent, Grande recalled, "When I met Celine, she was like, 'When I saw you, I peed.' It was so funny."
