Bruno Mars feels the sting of Rosé’s chemistry with new partner

Bruno Mars reacted to Rosé’s sizzling chemistry with her new on-screen partner, Evan Mock, in the music video for her latest single, Toxic Till the End.

Ahead of the video’s release on December 6, Rosé shared a behind-the-scenes photo on social media featuring her and Mock sitting across each other in a dimly lit room.

Captioning the post with "Call us what we are," the BLACKPINK star sparked curiosity and excitement among fans. However, it was Mars’ comment that stole the spotlight.

"Wait a minute!!! Who TF is that???" the Talking to the Moon hitmaker jokingly wrote.

His playful reaction led to a flurry of fan responses, with many joining in on the fun.

"Bruno playing 'When I Was Your Man' now, haha," one fan quipped.

Another joked, "Bruno Mars’ next song title: 'When I Was Your Man in APT.'"

"This album should be called 'Emotional Damage,'" a third fan teased.

"Bruno, you should write a song about this, haha," another suggested.

Some fans even referenced lyrics from APT, Mars and Rosé’s previous collaboration, with one writing, "Bruno be like: 'Don’t you want me like I want you, baby, don’t you need me like I need you now…'"

Rosé’s new music video features undeniable chemistry with Mock, who plays The Ex.

Rose dropped her debut solo album, Rosie, amid the chart-topping success of APT, her earlier global smash hit with Bruno Mars.

APT continues to garner love from fans amid Rose’s new releases, thanks to its infectious melody and the duo’s charismatic interplay in its music video.
