The iHeartRadio Music Festival is part of iHeartMedia’s series of major music events, which also includes the nationwide iHeartRadio Jingle Ball Concert Tour, the iHeartCountry Festival, and the iHeartRadio Music Awards. As usual, the 2026 iHeartRadio Music Festival took place on the 18th and 19th in Las Vegas, bringing together a huge lineup, especially with the appearance of K-pop superstars who have recently returned from their mandatory military service.

BTS was one of the most highly anticipated groups at this major music festival, as it had been seven years since their last appearance here. And the members truly did not disappoint their fans. On the 18th, BTS appeared at the festival’s first night at T-Mobile Arena in Las Vegas, delivering a series of their iconic songs.

Opening with “SWIM,” the title track from their latest album ARIRANG, BTS had the au∂ιєnce roaring with excitement. They followed it with an energetic performance of “2.0” and their iconic 2019 debut song “Mic Drop,” before wrapping up their fiery set with “FYA.” BTS also sent heartfelt greetings and thanks to the fans who were there at the arena to support the artists that day, making the atmosphere even more amazing.

While their performance on stage was the highlight of iHeartRadio 2026, a recent behind-the-scenes moment between V and Jungkook has also υиєχρє¢тє∂ly caught the attention of fans around the world!

Specifically, a video capturing the two youngest BTS members’ reaction to Zara Larsson’s performance of “Symphony” is going viral on social media. Notably, the moment took place just minutes before BTS was set to take over the stage from Zara and perform next. Unlike their serious and focused image on stage, Jungkook and V showed a much more relaxed side behind the scenes as they enjoyed the music together.

In the video, the two kept dancing and flashing bright smiles along to the music. At one point, Jungkook and V even held hands and spun around together, happily playing around as if they were au∂ιєnce members enjoying their favorite artist’s performance rather than the headliners of the event themselves. The candid moment captured of the superstars quickly spread across social media afterward, leaving many fans delighted and captivated.

On social media, the video received plenty of cute and excited comments, including:
