Did BTS Lip sync?
Naw, they just know how to perform. They are the definition of true entertainment. They practice for 10 hours(maybe even more) for days on end. And not only for the AMAs. They’ve been doing this since way before they debuted in 2013. Just because it’s out of the norm to be able to sing and dance at the same time for some of people, doesn’t mean it can’t be done. BTS has proven that every time they step on the stage.
Don’t believe me? Check out the rest of their live performances. They got a bunch.
