K-pop fans were sent into a frenzy when Bruno Mars made a playful comment on Rosé's Instagram post, reacting to her undeniable chemistry with Evan Mock in her latest music video for the single 'Toxic Till The End.'

The Blackpink star's new track dives deep into the emotional turmoil of a toxic relationship, weaving a story of love, betrayal, and heartbreak. The accompanying music video showcases Rosé crossing paths with her ex-lover, played by model and actor Evan Mock, in a moody forest setting. As the narrative unfolds, it becomes clear that their relationship was doomed by infidelity, culminating in a poignant ending.

Fans were quick to react when Rosé shared two stills from the music video on her social media. One image, in particular, captured the duo sitting intimately close to a fireplace, creating a cinematic and emotional moment. Captioned with the cryptic phrase, “Call us what we are,” the post garnered a flood of comments from fans who couldn't help but notice the palpable chemistry between Rosé and Mock.

Among the sea of comments, Bruno Mars’s response stood out. Having previously collaborated with Rosé on the smash hit 'APT,' the Grammy-winning artist brought his humor to the mix, writing, “Wait a minute.

The lighthearted interaction between the two artists delighted fans, reigniting fond memories of their collaboration. Their track 'APT' was a massive success, blending Bruno's signature groove with Rosé’s distinct vocals, and many are hoping to see the duo team up again in the future.

'Toxic Till The End' is part of Rosé’s new album 'Rosie', which delves into themes of love, loss, and self-discovery. With its cinematic visuals and emotional depth, the single is already making waves in the music industry. Evan Mock’s appearance in the video has also drawn praise for his compelling portrayal, making him an ideal counterpart to Rosé’s heartfelt performance.
