After a specific video spread online following Jennie’s Summer Sonic 2026 performance, OA Entertainment issued an official notice on August 18 stating that it would respond to posts targeting Jennie that contain false information, defamation, malicious slander, malicious editing or manipulation of photos and videos, and violations of privacy and personal rights.
The key point is that the agency mentioned civil and criminal legal proceedings. However, the notice did not establish that a specific Summer Sonic video was manipulated, nor did it identify a particular account.
Jennie’s Summer Sonic Appearance Is Confirmed by Official Records
JENNIE is included in the 2026 artist lineup on the official Summer Sonic website. Sony Music Japan also announced Jennie’s appearance on February 2, 2026, listing the event dates as August 14–16. Multiple reports state that Jennie performed on August 14 at ZOZO Marine Stadium in Chiba, Japan.
The Scope of OA Entertainment’s Response
OA Entertainment stated that it would monitor relevant posts and accounts, collect evidence, and pursue legal action—including civil and criminal proceedings—depending on the nature and severity of each matter.
The official notice gave the following examples of conduct subject to response:
- Repeatedly posting, reposting, or distributing specific photo or video scenes
- Maliciously editing or reworking physical features
- Distributing content that combines insulting expressions with false information
The agency also stated that it would not reach settlements or show leniency. However, publicly available material does not establish case filing numbers, confirmation from investigative authorities, or whether any judgment has been issued.
The scope of the legal-response notice and the authenticity of a specific video must be verified separately.
What Has Not Yet Been Confirmed
The authenticity of a specific performance video circulating online has not been confirmed. Some reports have raised the possibility of manipulation using AI or editing technology, but OA Entertainment’s official notice did not explicitly confirm that the Summer Sonic video had been manipulated. A direct official connection between the notice and the video in question has also not been confirmed.
Therefore, the conclusions currently supported by available information are as follows:
- Jennie’s appearance at Summer Sonic 2026 is confirmed by official materials.
- OA Entertainment announced a policy of pursuing civil and criminal action against a broad range of posts involving false information, malicious editing, and violations of privacy and personal rights.
- The authenticity of the specific video at the center of the controversy and the details of any legal proceedings have not been confirmed.
Reposting or extensively circulating the video or image in question may cause additional harm, regardless of whether it is being shared for fact-checking purposes. Caution is advised.
