Katy Perry performs Harleys in Hawaii in the toilet

Katy Perry’s “Harleys in Hawaii” has seen a resurgence in popularity, thanks to TikTok.

A slow version of the hit song — specifically, the part where Katy Perry sings “you and I” and holds the last note — is being used on various videos on the social media platform.

The song’s sales have soared according to Official Charts Company. It’s also tops the list of Katy’s most popular track on Spotify currently.

Charlie Puth co-wrote the song and acknowledged the trend by duetting with one of the TikTok videos with the caption, “Why do all of these songs I made years ago keep blowing up all of the sudden?”

Charlie said, “I mean I’ll take it!!”
