Girl group Twice’s Chaeyoung and Tzuyu took to the V app to sing the viral “Pen Pineapple Apple Pen” song on Friday.

Chaeyoung and Tzuyu mysteriously uploaded the video without prior notice, simply lip-syncing to the song in their dorm room.

The viral Japanese “Pen Pineapple Apple Pen” song has been dubbed the next “Gangnam Style,” after the original video earned an impressive 11 million views within a few days, but now it’s become a trending internet challenge to sing and dance along to.
