Bruno Mars reposted a fan-made collage of him and BLACKPINK’s Rosé on his Instagram story on Thursday, April 17, 2025. The pictures seemingly showed the two singers from when they were preparing and promoting their collaborative song APT.

Fans who saw the pictures were happy to see the friendship between the two singers and appreciated the love and respect they had for each other. However, some fans speculated that the friendship between Mars and Rosé was one-sided but were glad to see Mars upload the pictures. They had been speculating that Bruno Mars didn’t allegedly appreciate the friendship as much as the BLACKPINK star did.

The speculations began after watching a video of Rosé trying to video call Bruno Mars at the 2025 Coachella during Lady Gaga’s performance. Since the Uptown Funk singer didn’t answer the call, netizens began speculating about the friendship. However, they were happy to see the photos that Bruno Mars had uploaded.

Fans took to social media to react to the photos, with many asking others not to “speak about their friendship.” They defended Mars and the K-pop star’s friendship, urging others not to speculate about it.

“This man doesn’t play about Rosé, don’t ever speak about their friendship.”

More fans and netizens expressed their happiness about Bruno Mars’ recent post while defending the K-pop idol and her friendship with the singer. One fan remarked on the timing of Bruno posting a fan-made collage just days after some were trying to undermine Rosé’s reputation.

Bruno Mars is known for supporting Rosé, especially when the negative comments arise, showcasing their bond and mutual respect.
