NCT Jaehyun Receives Backlash Amid Allegations of Being BLACKPINK Rosé’s Toxic Former Boyfriend

Jaehyun at the Center of Controversy Over Rosé’s Album Claims

The K-pop world is buzzing with allegations surrounding NCT’s Jaehyun, who has been labeled the “toxic ex-boyfriend”mentioned by BLACKPINK‘s Rosé in her latest album, Rosie. This attention follows the release of leaked information suggesting a connection between Jaehyun and Rosé’s personal experiences depicted in her track “toxic till the end.”

Allegations Emerge from Leaked Videos

The drama unfolded over the weekend when a purported YG Entertainment employee leaked several videos of BLACKPINK during their training days, alongside claims that Jaehyun is the toxic ex referred to in Rosé’s song. The source went so far as to explicitly state, “Rosie’s toxic ex is Jaehyun.”

Background on the Leaked Information

Interestingly, this former employee has a track record of leaks, previously sharing information about BLACKPINK member Jennie’s rumored relationship with BTS member V. Despite the intensity of the current allegations, both Jaehyun and Rosé have refrained from publicly addressing the claims made by the leaker.

Fan Reactions and Backlash

The allegations have prompted a wave of negative comments on Jaehyun’s Instagram account, showcasing the volatile nature of fandoms in the K-pop industry. Fans have expressed their opinions actively, with comments such as:

“Give Rosé back her Tiffany rings, boy.”

“You broke Rosé’s heart?”

Social Media Commentary

And this is why it’s never “just a joke” because at the end of the day it’s jaehyun who ends up getting hate directly… and it’s nctzens themselves who constantly spread these rumours and people end up taking it seriously and lash out at him when he isn’t even an active idol 🫤 pic.twitter.com/8nITV6GH2X

Speculations About Rosé’s Ex

Rosé has consistently avoided revealing the identity of her song’s subject. Fans have engaged in relentless speculation, connecting her lyrics to various names, including Jaden Smith and Jason Cho. Jaehyun’s involvement in this ongoing dialogue is compounded by years of fandom “shipping”cultures and parallels drawn from their work. Notably, Jaehyun’s 2024 album featured a track titled “Roses” , which fans interpreted as a possible reference to Rosé.

Lack of Concrete Evidence

Despite extensive fan theories and speculation, there remains no verifiable evidence supporting a romantic relationship between Jaehyun and Rosé. Both idols have chosen to maintain their silence amidst the fervor surrounding these rumors.

Current Endeavors

As of now, Jaehyun is scheduled to complete his mandatory military service in May 2026, while Rosé continues to shine as a solo artist, capitalizing on the success of Rosie and preparing for BLACKPINK‘s anticipated comeback.
