Frankie Grande unveils Celine Dion's shocking reaction after watching Ariana mimic her

Ariana Grande's brother Frankie Grande revealed Celine Dion's hilarious reaction to her own impression by the Bye singer.

The Wicked star is known for her impressive celebrity impressions and has famously mimicked pop stars including Britney Spears and Celine's voices and facial expressions flawlessly.

During Frankie's latest appearance on The Tonight Show, he recalled that Dion met him in Las Vegas shortly after Ariana had performed her impression on Jimmy Fallon’s show.

The Heart Will Go On singer revealed that after seeing Ariana's mimic she laughed so hard that she "peed."

“The first time I met Celine Dion was right after Ariana was on your show and she did her Celine impersonation,” Frankie told Jimmy.

​He went on to share, “And so I was there in Vegas and Celine comes literally running up to me and she’s like, ‘Oh my God, Frankie, you have to tell your sister when she did me on Jimmy Fallon I peed.’

​"She goes, ‘I was laughing so hard I peed myself. I peed,'" he added.

​Ariana has been spotted on multiple occasions paying tribute to Celine while impersonating her.

​Back in 2018 when Ariana made an appearance on Carpool Karaoke with James Corden, she sang a part of Dion’s hit song from 1989 titled It’s All Coming Back to Me Now, which she began with a playful stage introduction.

​Moreover, when Ariana celebrated her 31st birthday by sharing a childhood video, it also included a sweet nod to her favorite singer.
