Although Jungkook, BTS, and Justin Bieber have never had a major collaboration or many interactions over the years, there has been no shortage of support and respect between them. In 2020, Justin referred to the members as “my boys” and congratulated them as they achieved global success with the music video “ON” and the album Map of the Soul: 7. During the ending of the World Cup Halftime Show in July this year, Justin and BTS were also seen walking back to the main stage together to greet the au∂ιєnce.

More recently, Justin Bieber υиєχρє¢тє∂ly reposted a video capturing Jungkook’s sizzling performance, in which he showed off his six-pack abs and toned physique, on his personal account with 280 million followers. The Canadian singer’s move immediately sent fans into a frenzy.

Social media was flooded with excited reactions such as: "HELP, why is justin bieber reposting shirtless jungkook?", "I CANT BLAME HIM", "he actually DID!? And he doesnt have that much reposts either.. this is fяєαкing me out ngl but whatever.", "All these interactions but no collab? When guys??", "Jungkook finally won his fanboy side", "Even JB can't resist from JK abs",...

What made it even more interesting was that fans remembered this was not the first time Justin Bieber had directly mentioned Jungkook or shown him special support. Back in 2019, Justin publicly wished Jungkook a happy birthday through a post on X, even jokingly predicting how social media would explode when the Prince of Pop and one of the world’s biggest K-pop stars interacted with each other.

Justin Bieber’s birthday tweet to Jungkook that year received more than 1.2 million likes. Even in 2026, people are still bringing it up and sharing it as a memorable moment, showing how a major Western pop star publicly acknowledged Jungkook. At the time, 22-year-old Jungkook must have been thrilled to receive birthday wishes from an idol he had long admired, but he did nothing more than retweet the post, presumably because he was too shy to say anything else.

Six years later, once again around Jungkook’s birthday, Justin Bieber sent social media “go crazy” by giving a shout-out to his incredibly seductive moment. This time, fans have another suspicion: perhaps Jungkook isn’t the only huge Justin Bieber fan after all, and Justin himself may actually be a big fan of Jungkook in return. If that is the case, BTS’ Golden Maknae may just be the most successful fanboy of all time.

Interestingly, Jungkook’s reaction to Justin Bieber’s attention this year was completely different from his quiet response years ago. After discovering that Justin had reposted the moment showing off his abs, Jungkook took a screenshot and posted it to his Instagram Story with a “?!” — looking genuinely ѕнσ¢кed. Fans now also believe that the possibility of the two artists finally connecting for a collaborative project may be closer than ever.

As these stories resurfaced for discussion, fans could not stop talking about them across social media:

- Jungkook is literally thee artist of all artists whether they are SENIORS or JUNIORS. The star factor is CRAZY

- Seven years later and we STILL need that Bieber x Jungkook collab. Imagine the vocals if they actually sang together!

- Same energy. Justin greeting Jungkook a happy birthday out of nowhere and Justin reposting shirtless Jungkook out of nowhere

- Thank you Justin but we actually need more specific action like a collaboration between 2J, so when?

- The fact that Justin has been supporting Jungkook since 2019 and is still doing it years later… Jungkook really manifested this friendship

- Jungkook’s ‘?!’ Instagram Story is кιℓℓing me. He still looked genuinely ѕнσ¢кed that Justin Bieber reposted HIM

- At this point, I don’t know who is the bigger fan — Jungkook of Justin or Justin of Jungkook. They need to stop teasing us and just give us the collaboration already!

- Imagine being 22 and getting a birthday shout-out from Justin Bieber, then six years later having him repost your shirtless concert video. Jungkook is literally living every fanboy’s dream

- There have been SO many little interactions between them over the years. A collab between Jungkook and Justin Bieber would honestly be iconic. I need this to happen ASAP!
