Jimmy Fallon reunites with BTS after 4 years and fans can’t get enough of one moment

Jimmy Fallon has reunited with global K-pop stars BTS on The Tonight Show Starring Jimmy Fallon, marking their first appearance together in over four years.

The highly anticipated return comes as BTS step back into the spotlight following their military service hiatus, and the moment is already taking over social media.

The two-night special sees the group promoting their new album ARIRANG, their first major release in years.

BTS are also delivering two performances filmed inside New York’s Guggenheim Museum, with “SWIM” airing first and “2.0” set for the following episode.

But while the performances are drawing attention, it is one unexpected detail from the interview that fans cannot stop talking about.

The group appeared wearing house slippers, introducing Fallon to the Korean custom of removing shoes indoors, a moment that quickly went viral for being both wholesome and culturally meaningful.

It even ties back to their music, with a lyric in their track “Aliens” referencing the tradition.

The reunion itself carries emotional weight, with Fallon catching up with the group after years apart.

BTS reflected on their hiatus, their return and what it means to reconnect with their global fanbase, known as ARMY.

They also spoke about ARIRANG, an album inspired by a traditional Korean folk song, signalling a return to their roots while continuing to evolve globally.

As expected, the appearance also delivered classic BTS energy, mixing humour, chaos and heartfelt moments, from playful banter with Fallon to surprising fans in the audience.

It is that combination of nostalgia, cultural moments and comeback energy that is driving the clip across platforms.

With performances, emotional reflections and viral moments all in one, BTS’ return to Fallon’s show feels less like a guest spot and more like a full-circle moment.
