i-dle continues to rack up major YouTube milestones. On August 7 at around 5:16 p.m. KST, the music video for "Tomboy"—one of their most iconic tracks—surpassed 400 million views on the platform.

The 2022 release is now the group's third video to hit the 400 million mark, following "Queencard" and "Nxde." The achievement underscores how much staying power "Tomboy" has maintained over the years. The song was a defining moment in i-dle's career, becoming a fan favorite and a staple of their live performances.

This viewership milestone reflects the group's consistent pull on YouTube and their global fanbase. While many K-pop groups see their music videos accumulate views fastest in the months after release, i-dle's continued growth on "Tomboy" suggests the track has become a timeless part of their catalog—the kind of song fans return to regularly.

i-dle has had a strong track record with high-performing music videos. The group's ability to reach these billionth-view thresholds multiple times speaks to both their popularity and their talent for creating memorable, rewatchable content. "Tomboy" in particular stands out for its confident energy and the group's tight choreography, making it the kind of track that appeals to longtime fans and new listeners alike.

The group has been active with new material and performances, so this milestone comes as they continue to expand their presence in the K-pop space. With three videos now in the 400 million club, i-dle remains one of the more successful girl groups on YouTube in terms of sustained viewership.
