K-pop girl group Blackpink broke a YouTube record on Wednesday, with their music video "Ddu-Du Ddu-Du" crossing two billion views.

This is a first for a K-pop group on the platform.

Released in June 2018, "Ddu-Du Ddu-Du" is the lead track on the quartet's first EP, Square Up. It was a massive commercial success and was voted Song of the Year in a Gallup Korea survey that year.

In terms of YouTube views, however, it still lags behind Psy's "Gangnam Style", which was a monster hit in 2012 and is the most viewed music video for a K-pop solo artiste. It has clocked 4.6 billion views.

Another Blackpink music video, "Kill This Love", has 1.7 billion views.
