The famous American singer Katy Perry angered the ARMY's after joking at the KIIS FM Jingle Ball. The BTS fans found what the singer said as offensive.

After BTS performed, Perry took over the stage and said: "Most of you get to stay up late past your bedtimes." Followed by what the ARMYs said as an evil laugh. 

One fan tweeted, "That's the fakest "just kidding" laugh I've ever heard, it was rude of her."

It was also reported that some of the ARMYs went home during Katy Perry's performance and not a single one was singing along with her. However, some of the fans also defended the Hollywood singer saying it was just a light-hearted joke.

Is it an innocent remark or did the singer really mean anything by it? What do you think?
