Jaehyun’s Cousin in Bikini Video Identified as Dating Rumor Is Clarified

NCT member Jaehyun’s vacation video drew attention on June 26, 2026, after viewers focused on a scene showing him entering the sea with a woman in a bikini. The Jaehyun Dating Rumor was later clarified through social-media comments identifying the woman as his cousin, with Jaehyun writing, “My dearest cousin.”¹

The issue began after Jaehyun uploaded vacation photos and short videos to his social media account. Multiple Korean entertainment outlets reported that the post included scenes from a seaside trip, including surfing and a short clip in which Jaehyun and a woman with long hair were seen going into the water together.² The woman’s appearance in a bikini led some online users to speculate about whether she was his girlfriend, but the explanation that followed identified her as a family member, not a romantic partner.³

Bikini Video Sparked Online Speculation

The focus of the discussion was not the entire vacation post but a specific moment from the video. Reports described the clip as showing Jaehyun and the woman side by side near the sea before going into the water. Star Today reported that the woman was wearing a bikini and had long straight hair, and that the dating rumor emerged after the images and video were posted on Instagram on June 26, 2026.¹

Xports News also reported that Jaehyun uploaded the vacation content without a detailed explanation, which left room for viewers to speculate about the identity of the woman seen with him.⁴ The outlet said discussion spread among some fans after the clip circulated, with the woman’s identity becoming the main subject of attention rather than the vacation itself.

The wording used in several reports indicates that the rumor developed from interpretation of the video rather than from any confirmed dating information. Newsen summarized the sequence as a short diving video becoming a topic of conversation, followed by questions from some viewers about whether the woman could be a girlfriend.³ No source material provided any confirmed evidence of a romantic relationship.

Jaehyun and SM Producer Said She Was His Cousin

The rumor was addressed after a producer affiliated with SM Entertainment commented on the post, explaining that the woman was Jaehyun’s younger cousin. Xports News quoted the producer as saying in Korean that Jaehyun had likely posted the memory with good intentions after spending time with his cousin during a difficult schedule.⁴

Jaehyun then added his own direct clarification in English: “My dearest cousin.”¹ The same comment was cited by multiple outlets as the key point that ended the speculation. Star News reported that both the SM Entertainment producer’s comment and Jaehyun’s own comment identified the woman as his cousin.⁵

Ilgan Sports characterized the matter as an online dating rumor that Jaehyun directly clarified, reporting that the speculation spread after users focused on the vacation video and that the issue was brought to a close after he stated the woman was his cousin.⁶ TWIG24 similarly reported that the identity of the person in the video was settled through comments from the agency-side producer and Jaehyun.²

The available source material does not include a separate formal statement from SM Entertainment. The clarification described in the reports came through social-media comments, including the producer’s explanation and Jaehyun’s own comment. The distinction matters because the public resolution of the rumor, as reported, came from comments attached to the social-media discussion rather than a long-form agency announcement.

Reports Framed the Case as a Brief Misunderstanding

Several outlets framed the incident as a fast-moving misunderstanding linked to the speed of online interpretation. The clip was drawn from a personal vacation post, and the speculation centered on the visual context of a woman appearing with Jaehyun in swimwear. Once comments identified her as his cousin, the reports described the dating rumor as effectively resolved.⁶

The coverage also noted that the vacation content included ordinary leisure scenes such as sea activities and surfing. TWIG24 reported that Jaehyun posted photos and short videos of himself enjoying the sea and surfing on June 26, 2026.² Those details place the disputed clip within the broader context of a vacation post rather than a standalone announcement or promotional release.

Star News added background that Jaehyun entered military service in November 2024 and has served as a military band member.⁵ That detail was included in the outlet’s broader entertainment-news briefing, but the central point of the June 26 reports remained the clarification of the woman’s identity in the vacation video.

The available reports do not state that Jaehyun deleted the post, issued any further explanation, or confirmed any relationship. They consistently identify the woman in the clip as his cousin and describe the dating rumor as speculation that followed the vacation upload. The quoted comment, “My dearest cousin,” is the clearest direct statement from Jaehyun included in the source material.¹

In conclusion, the June 26 discussion around Jaehyun’s bikini video centered on a brief dating rumor triggered by a vacation clip. Based on the reports provided, the woman seen with him was identified as his cousin, and Jaehyun’s own comment clarified the situation directly.
