PETALING JAYA — Fans of K-pop superstars BTS have expressed concern after a video showing member Kim Tae-hyung, also known as V, with an e-cigarette made its rounds online.

Fellow BTS member Jimin had posted a Christmas-themed video clip to BTS' official Twitter account.

The original tweet was quickly deleted after eagle-eyed fans pointed out the blue Juul device visible next to V in the clip, but not before screenshots and reuploads began spreading like wildfire online.

Fans of BTS, known as ARMYs, were divided over V’s possible e-cigarette habit, with some saying that it could jeopardise his voice and subsequently, his career.

Others argued that V, 23, had every right to use e-cigarettes as a legal adult and that fans should mind their own business.

Some ARMYs added that they wouldn’t be surprised to find out that V had taken up vaping as the Boy with Luv singers have highly stressful and busy lives.

In a recent livestream on Naver, V revealed the group's ongoing dilemma with obsessive fans who would dig up their flight information and buy seats in the same cabin so that they could stalk the group. MALAY MAIL
