BTS dance to 'Fortnite' on 'Tonight Show,' perform on 'GMA'

Sept. 26 (UPI) -- South Korean boy band BTS took over The Tonight Show and then Good Morning America, performing their hit single, "Idol."

On The Tonight Show Tuesday, BTS also performed "I'm Fine" and tried their best alongside host Jimmy Fallon to imitate dance moves from popular video game Fortnite.

The Fortnite challenge involved the group and Fallon watching dance moves from the game before attempting to perform them, including The Flapper, Electro Shuffle and Best Mates, among others.

BTS then performed the Ride the Pony and attempted to teach Fallon the choreography behind "Idol."

Fallon interviewed the band, with each member -- RM, J-Hope, Jimin, Jin, Jungkook, V and Suga -- introduce himself.

The band members told Fallon about speaking in front of the United Nations, the best things they experienced in New York City and what they want to accomplish in the future, including going to the Grammy awards.

"I was like so nervous," RM said about the U.N. speech to promote their "Love Yourself" message. "I was holding up the paper and you could see my hands shaking."

On Good Morning America on Wednesday, the band was surrounded by screaming fans as they took to the dance floor for "Idol" in a high-energy, highly-choreographed performance.

The band resumes their tour on Friday in Newark, N.J., in support of their most recent album, Love Yourself: Answer.
