TWICE member Nayeon sent fans into a frenzy with an unexpected appearance at Charlie Puth’s Seoul concert, joining the American singer on stage for a live performance in front of approximately 38,000 people.

Puth brought his Whatever’s Clever! World Tour to Goyang Stadium on October 11, where the surprise collaboration became one of the evening’s standout moments.

Without any prior official announcement, Nayeon suddenly appeared on stage to thunderous cheers from the crowd. The two artists then performed Puth’s hit song We Don’t Talk Anymore together, giving fans a rare opportunity to see the singers share the stage.

Rehearsal clips fuelled speculation before the show

Although Nayeon’s appearance was not officially announced in advance, some fans had begun to suspect that a special guest might be joining Puth.

Short clips from rehearsals circulated through online communities and social media ahead of the concert. Viewers speculated that the unidentified female voice heard in the footage belonged to Nayeon.

Those rumours were confirmed when the TWICE star appeared during the actual performance, turning fan speculation into one of the night’s biggest surprises.

The unexpected duet also highlighted the connection between the two artists, whose collaboration brought together fans of K-pop and Puth’s pop music.

Charlie Puth previously praised TWICE and K-pop

Nayeon’s appearance came after Puth had spoken about his growing interest in TWICE and the wider K-pop scene.

In an earlier interview, the singer revealed that he had been listening to the group’s music, saying, “I’ve been listening to a lot of TWICE’s music lately.”

He also shared his appreciation for the musical craftsmanship behind K-pop productions.

“I love K-pop. Sometimes I even listen only to the instrumental because I want to understand how the producer structured the song. I learn a lot from it, and I enjoy listening to it,” Puth explained.

His comments offered insight into his interest in the genre, making the onstage collaboration with Nayeon an especially exciting moment for fans.

‘We Don’t Talk Anymore’ becomes a concert highlight

The performance of We Don’t Talk Anymore quickly emerged as a memorable highlight of Puth’s Seoul stop, with Nayeon’s unannounced arrival adding an extra layer of excitement to the show.

For fans who had followed the rehearsal rumours, the duet provided a satisfying reveal. For those who had no idea a special guest was coming, it delivered a genuine surprise.

Nayeon’s appearance ultimately gave concertgoers a rare live collaboration between the TWICE singer and Charlie Puth, turning an already anticipated tour stop into an especially talked-about night.
