251211 ROSÉ AND BRUNO MARS SPILL SECRETS BEHIND THE MAKING OF ‘APT.,’ 2025’S BIGGEST GLOBAL HIT | Billboard

Gasped when i read this:

**Are there other songs you two worked on that didn’t make it on this album — or that you’ve worked on since this album?**

**Rosé:** (*Laughs*.)

**Mars:** Oh, yeah, there is. And we love that song that we worked on — I won’t say the title… We’re just trying to figure out when, or how.

**Bruno, you said recently that “APT.” “birthed a new K-pop juggernaut named Bruno Mars.”**

**Mars:** I don’t know if you know this, but it’s different for me now in Korea.

**Tell me.**

**Mars:** Because of Rosie, it’s a different thing. They treat me a little different now over there. And like I said, I really gravitated toward the song because it had a piece of Korean culture and I thought that was magical.

**Rosé:** I went to your concert [in June 2023] a year before I met you, and I think a big part of what makes the whole crowd fall in love with Bruno was that we all felt how passionate he was toward our culture. I was blown away. I’d never seen a concert where it was so catered to wherever he was. We were in Korea and he had written this whole song based on our…

**Mars:** I had to let these Korean girls *know*.

**Rosé:** He was letting them know! And as we were working on this song, he has shown me and my culture so much love and appreciation and acceptance; he really wanted to dive deep into that. He always reminds me, even now, how much we need to embrace the culture and how important it is and how that is what the people want to hear. They want to be introduced to this beautiful culture that we have.

**Mars:** No one says it, but I feel like Rosie is the first time we’ve seen this. The last time we’ve seen something to this effect was “Gangnam Style.” I still think that was an amazing thing to happen, this guy comes out and he’s talking about Gangnam style and the whole song is in Korean and that’s the learning lesson, the rock star-ness of that. This is what *we* do, this is how *I* talk, this is what *we* look like, this is how *we’re* dancing over here — and watch me sweep the nation with this s–t. And he did. “APT.” with Rosie, I’ve never felt this before, I’ve never seen this before, where Rosie is this Korean girl that introduced this thing to people who don’t know about it, including myself. And that’s been the most enjoyable part for me. Seeing everybody react… that is magic to watch.
