Michael Bublé recently shot down retirement rumors, but if he does ever decide to hang up his mic for good, we know the perfect person to take over for him: Troye Sivan. Although the Australian pop star's singing style doesn't have much in common with the Canadian crooner, his recent impression of Bublé has us (and his legions of fans) cracking up with the accuracy.

To celebrate Ariana Grande's massive hit "Thank U, Next" reaching the top of the charts, Sivan - who collaborated with her on the song "Dance to This" - posted a 10-second clip of him singing her song in Bublé's voice. "Thank you, next," he repeats in a deep voice. "Because I'm so f*cking grateful for my ex." Who knew Troye Sivan impersonating Michael Bublé singing Ariana Grande would be our new favorite song?! Watch it ahead, then see how Grande herself reacted to the hilarious video.
