BLACKPINK’s Rosé is facing heavy online backlash after showing support for Bruno Mars. A simple post turned into a full blown debate. Fans and critics began questioning her friendship with the singer and her loyalty to her own group.

The reaction started after Rosé shared a post supporting Bruno Mars’ new music. Since their hit collaboration APT., people have been watching her closely. Some netizens now claim she talks about Bruno too much and puts him above BLACKPINK.

On January 9, Bruno Mars released I Just Might. It is the first single from his upcoming album The Romantic, which drops on February 27. The song gained massive attention fast. The music video crossed a million views quickly. Fans praised its smooth retro sound and classic Bruno Mars style.

Many listeners were happy to see Bruno return to solo music after Silk Sonic. The excitement around his comeback was strong. Rosé joined in by publicly supporting the release.

That is when the backlash began.

Some netizens accused Rosé of being obsessed with Bruno. Old clips resurfaced online. One interview in particular went viral again. During a word game, Rosé said “Bruno” for the letter B instead of BLACKPINK or BLINKs. Critics used this moment to claim she values him more than her group.

On X, comments became harsh. Some people mocked her excitement. Others accused her of clinging to the collaboration. A few even suggested her success is tied to Bruno, not her own talent. Many pointed out that she does not post about her group members in the same way.

At the same time, many fans rushed to defend her.

Supporters said she is allowed to show appreciation for a friend and collaborator. They argued that supporting Bruno does not mean she loves BLACKPINK any less. Fans called the hate unnecessary and unfair. They said Rosé is being targeted simply for being open about admiration.

Others reminded critics that Rosé has always shown pride in her group. One post does not erase years of loyalty. To them, the backlash feels exaggerated and cruel.

APT. has already boosted Rosé’s global reach. The collaboration introduced her to wider audiences and strengthened her presence outside K pop. Fans believe that working with Bruno Mars helped show her versatility, not replace her identity.

For now, Rosé remains caught in the middle of online noise. A post meant as support turned into a loyalty test. And once again, the internet proved how quickly admiration can be twisted into controversy.
