Daesung Denies Dating Rumor With Heo Young-ji After MAMAMOO Concert Sighting

Daesung’s side has denied a dating rumor involving Heo Young-ji, stating that the two are not in a romantic relationship. The Daesung dating rumor emerged after images and video of the two attending a MAMAMOO concert spread through online communities and social media on June 22, 2026.¹

R&D Company, Daesung’s agency, said the two are “only close colleagues” and that “the dating is not true,” directly rejecting speculation that followed the concert sighting.¹ Multiple Korean entertainment and news outlets reported the same position on June 22, citing Daesung’s side as saying the relationship was based on professional friendship rather than romance.²

The rumor centered on Daesung, a member of BIGBANG, and Heo Young-ji, a member of KARA. Reports said the speculation began after the two were seen at a MAMAMOO concert held at Olympic Hall in Olympic Park, Songpa-gu, Seoul.³ The sighting circulated online, where some users interpreted their appearance together as a possible sign of a romantic relationship.

Daesung’s agency moved quickly to deny that interpretation. Xportsnews reported that R&D Company explained the two had built a friendship after appearing through Daesung’s YouTube content, Jibdaesung, and went to watch the MAMAMOO concert together.¹ Dong-A Ilbo also reported that the agency described the concert attendance as an outing between people who had become close through Jibdaesung, rather than evidence of dating.⁴

The official response was brief and direct. R&D Company’s position, as reported by Xportsnews, was that Daesung and Heo Young-ji are “only close colleagues” and that the dating claim “is not true.”¹ OSEN likewise reported Daesung’s side as saying they are “close colleagues,” reinforcing the denial across more than one outlet.²

Concert Sighting Sparked Online Speculation

Reports across several outlets described the origin of the rumor in similar terms: photos or footage from the MAMAMOO concert appeared on online communities and social platforms, prompting some viewers to raise dating speculation.⁵ The coverage did not cite any additional evidence beyond the public sighting and online discussion.

The context of the concert appearance also became part of the clarification. OSEN reported that Oh My Girl’s Hyojung was also known to have been at the scene.² iMBC Entertainment similarly reported that Hyojung was understood to have been present at the concert venue along with Daesung and Heo Young-ji.⁵ Korea Economic Daily reported that Hyojung was seated near Heo Young-ji, in addition to Daesung.³

That detail matters because the rumor was based on the interpretation of a concert attendance scene rather than an official personal announcement. Money Today reported that photos of Daesung, Heo Young-ji, and Hyojung watching the MAMAMOO concert at Olympic Hall spread through social media and online communities before Daesung’s side denied the rumor.⁶

The reports did not indicate that Heo Young-ji’s side issued a separate detailed statement in the provided material. The confirmed public position available from the cited reports is Daesung’s agency’s denial and explanation that the two are close colleagues.

Agency Frames Relationship as Collegial

R&D Company’s explanation placed the relationship in the context of Daesung’s YouTube content Jibdaesung. The agency said Daesung and Heo Young-ji became acquainted through that content and later attended the concert together.¹ Dong-A Ilbo’s report carried the same explanation, saying the two developed a friendship through Jibdaesung before going to the MAMAMOO concert.⁴

The denial followed a familiar entertainment-news pattern in which a public sighting generates online speculation, followed by a short agency clarification. In this case, the statement did not leave ambiguity about the agency’s position: Daesung’s side rejected the dating claim and described the relationship as a close colleague relationship.¹

Money Today reported that the rumor was effectively settled after Daesung’s side denied it.⁶ The available reports do not add further claims about a private relationship, future schedules, or any additional action from the agency beyond the denial.

As of the June 22 reports, the confirmed facts are limited to the concert sighting, the online spread of related images or footage, the presence of other acquaintances including Hyojung as reported by outlets, and R&D Company’s denial of the dating rumor. The official position remains that Daesung and Heo Young-ji are close colleagues, not a couple.
