Fans line up outside Staples Center ahead of BTS concerts in Los Angeles

K-pop band BTS just beat out Taylor Swift for the most watched YouTube video in a single day -- and are now bringing their world tour to Los Angeles.

After receiving more than 45 million views in 24 hours, the band's song "Idol," which features Nicki Minaj, beat Swift's record for the video, "Look What You Made Me Do."

After a show in Seoul, the global superstars are continuing their world tour across major cities in North America -- which include Los Angeles, Oakland, Fort Worth, Newark and Chicago in the U.S.

Four shows are scheduled at the Staples Center in Los Angeles as part of the band's "LOVE YOURSELF" tour, beginning Sept. 5 through Sept. 9.

Fans lined up for hours, some even days, ahead of the concert in Downtown LA.

From Stephanie Stanton:

Three letters, millions of adoring fans. Worldwide k-pop sensation BTS kicking off its sold out tour in Los Angeles.

Fans camped out hoping to get a spot near the stage.

"Where will you sleep? In this chair, in this very chair." said Boyle Heights resident Ashley Bonner. She and her friends have general admission tickets for Thursday's show. All of them sporting green numbers to mark their place in line.

"We all know kind of where we're at and whose been waiting the longest to try to get in there and try to get as close to the barricade as possible." said camper Nia Hendrix from Long Beach.

The seven member group has become a worldwide phenomenon. Their latest hit, idol featuring Nicki Minaj became the most watched Youtube video in a single day with 45 million views beating out Taylor Swift.

Fans call themselves the BTSarmy and explain why they love this boy band who sings mostly in Korean.

"It has really catchy beats and everything but there are songs that really get to me and that's all I really need when I'm having a bad day." said Bonner.

And tickets aren't cheap, $250.00 each for general admission. Some reselling for up to $4,000!

"Were you tempted at all to sell your ticket? Not me personally because I felt so proud that I gotten it and I wanted it so bad." said Brooke Borden.

A concert that has fans sleeping, camping and waiting at all costs. Hoping to see their favorite Korean boy band up close, live and in person.
