BTS is taking over the Big Apple.
Adoring fans known as the BTS Army camped out for days ahead of the free concert, which kicked off the show's Summer Concert Series.
“I've been here since Wednesday, so an entire week I’ve been here,” one person told Inside Edition.
The NYPD even helped warm up the crowd early Wednesday morning, playing a BTS song from a car's loudspeaker.
Police also tweeted to make sure fans stayed safe during the outdoor gig.
The boy band's takeover of Manhattan continues Wednesday with a performance on "The Late Show With Stephen Colbert” at the Ed Sullivan Theater where the Beatles once performed to screaming fans over 50 years ago.
The group's new video "Boy With Luv" recently beat Ariana Grande's record for most YouTube views in a single day with over 300 million views.
The concert was the No. 1 worldwide trend on Twitter Wednesday morning with more than 1 million tweets about it.
New York City and BTS have a special relationship as the band performed their biggest North American concert last fall at Citi Field in Queens, New York, where fans also camped out for days leading up to the performances.
