Ariana Grande showed off a set of flawless diva impressions on Saturday Night Live over the weekend, including takes on Rihanna, Whitney Houston and Britney Spears. She must have been prepared to make a few enemies, since pop stars don't always have a sense of humor about themselves. But thankfully, at least one of the women Grande skewered enjoyed the impression: Celine Dion. Grande claimed during a recent appearance on Elvis Duran and The Morning Show that Dion was so into the sketch that she told Grande, "When I saw you, I peed." It seems Grande is safe in Dion's heart ? for now.
