BTS’s Jin and Coldplay are proving once again that music truly knows no borders — and the internet is absolutely loving it.

On April 28, Coldplay’s official X (formerly Twitter) and Instagram lit up with a series of photos and videos from their 'Music of the Spheres' world tour, which kicked off at Goyang Sports Complex on April 16. Among the highlights? Two iconic photos featuring Jin and a couple of videos showing unforgettable moments between Jin and Chris Martin — including a heart-melting clip of them laughing, jumping, and celebrating on stage together.

Jin joined Coldplay as a special guest not once, but twice — on April 19 and for the grand finale on April 25 in Korea. Performing his emotional solo track "The Astronaut" (co-written with Coldplay!) and the crowd-favorite "My Universe," Jin captivated thousands with his soulful vocals and dazzling visuals, quickly becoming the talk of social media.

Chris Martin, who has long credited Jin for helping spark the BTS–Coldplay collaboration, didn’t hold back his admiration during the show, saying:
"Thank you for introducing us to BTS, for being so kind, and for singing with us today. I’ll always love you."

Their friendship isn't just for the cameras — it runs deep. Back in 2021, Jin casually complimented Chris’s beloved guitar during a New York trip, and Chris immediately gifted him the guitar he had played for over a decade. Since then, their bond has only grown stronger. In fact, ahead of the Seoul concert, Coldplay even teased Jin’s guest appearance by posting a photo of Wootteo, Jin’s adorable character, on social media — a nod to the plush mascot that Coldplay now brings to every concert around the globe.

After their emotional April 19 performance, Coldplay shared another heartfelt post featuring a snapshot of Jin and Chris performing together, captioned:
"Thank you Jin, thank you Seoul. We will never forget these moments," — topped off with a purple heart emoji.

Jin later posted his own behind-the-scenes moments from the concert on Instagram, sending fans worldwide into another frenzy. With every moment shared, Jin and Coldplay continue to prove that their magical collaboration and genuine friendship are truly one-of-a-kind — and fans are soaking up every second of it.
