Jung Kook Had No Idea What to Do After Justin Bieber Reposted His Viral Abs Video

Jung Kook's response to Justin Bieber reposting a video of him was, in its entirety, a screenshot and a question mark followed by an exclamation point: "?!" That might be the most relatable reaction possible.

The original clip came from BTS's show at SoFi Stadium in Inglewood, California, the final North American stop on the group's ongoing Arirang World Tour. Mid-performance, J-Hope walked over to Jung Kook and pulled open his unbuttoned shirt, putting his bandmate's abs on full display for the crowd. "What the fuck is going on right now," J-Hope laughed, leaning into the moment. "Oh my God… Guys, today is so special, right?" It's exactly the kind of unscripted stage chemistry that makes live BTS videos spread the way they do.

The clip went wide fast, and at some point it landed in front of Justin Bieber, who reposted it to his Instagram. Bieber and BTS aren't strangers: the two shared a stage earlier this year as part of the 2026 FIFA World Cup Halftime Show. But a casual Instagram repost of a shirtless workout-reveal moment is a different kind of interaction, which probably explains Jung Kook's very succinct response on his own Instagram Stories.

What's still ahead for the Arirang World Tour

The North American leg may be wrapped, but BTS has a long road ahead. The tour moves to South America next month, then swings through Asia in November and December. A final run of dates in Australia, Hong Kong, and the Philippines is scheduled to close things out next year, making this one of the most expansive tours the group has undertaken since their return from mandatory military service.

For now, though, the image of J-Hope grinning and pulling open Jung Kook's shirt while Justin Bieber silently hits repost is doing just fine on its own.
