With their number of subscribers surpassing 48.8 million as of Tuesday, they are just behind Bieber's 57.2 million , having edged ahead of DJ Marshmello's 48.7 million followers.

According to their management agency YG Entertainment, the group gained eight million new subscribers over the past three months.

This included 4.5 million after the release of their comeback single How You Like That, which saw them breaking several Guinness World Record titles and becoming certified as the most viewed video, music video and K-pop video on YouTube in 24 hours. It racked up 86.3 million views within 24 hours of its release in June.

They gained another 3.5 million subscribers following the release of Ice Cream - an international collaboration featuring American singer Selena Gomez - in August.
