N Seoul Tower lights up in pink to celebrate BLACKPINK's new song

STORY: The four-member group -- Jisoo, Jennie, Rose and Lisa -- released their new song on Friday (August 19), their first single in nearly two years, ahead of a planned nine-month world tour. The music video of the new song garnered over 21 million views on YouTube about four hours after its release.

The new album, Born Pink, set for release on September 16, pre-sold more than 1.5 million copies in a week, double the number of the group's first album, YG said. BLACKPINK will kick off their world tour in October and visit at least 26 cities through to June, performing to some 1.5 million fans.
