Justin Bieber reposts Jungkook's viral shirtless moment

Justin Bieber appeared to have joined BTS ARMY’s thirst over Jungkook’s viral six-pack moment.

Fans had already seen it. SoFi Stadium had already screamed about it. The internet had already turned it into a moment. And then the Baby hitmaker decided this one deserves a repost.

The youngest BTS member’s now-viral jacket reveal from BTS' ARIRANG World Tour has received an unexpected celebrity boost.

The Canadian pop star reposted a news publication’s video featuring the BTS star's eye-catching look from the group's Los Angeles concert.

The moment happened during the K-pop group's final North American show at SoFi Stadium on Sunday, September 6.

Jungkook, 29, appeared in a dark denim jacket worn open over his bare torso. During the performance, j-hope playfully got involved further, putting Jungkook's defined abs and full-sleeve tattoo on display.

Clips of the moment quickly spread across social media, with fans zeroing in on the playful interaction between the two bandmates.

And then the Grammy winning record producer entered the chat, sending a fresh wave of excitement through both BTS and Bieber fandoms.

The repost has attracted particular attention because fans noted that Bieber, 32, is extremely selective about what he reposts.

It has been observed that the Jungkook clip is only the eighth post the Yummy singer has ever reposted .
