A resurfaced video showing Tom Holland and Zendaya reacting to a surprise flash mob performance of David Guetta and Sia’s hit song “Titanium” is taking over social media, with the clip reportedly gaining more than 100 million views in just 24 hours.
The unexpected musical moment took place on June 24, 2026, during a fan event for Spider Man: Brand New Day at UGC Ciné Cité Bercy in Paris. French pianist and social media performer Julien Cohen led the performance from his piano as Britain’s Got Talent star Olly Pearson and a growing group of singers and musicians joined in.

What began as a piano performance quickly turned into a large live production. More performers gradually entered the venue, surrounding the event with a powerful arrangement of “Titanium,” the 2011 hit by David Guetta featuring vocals from Sia.
Video from the event captured Holland and Zendaya watching as the performance continued to grow around them. Neither actor joined the musicians, but both appeared surprised as they followed the unexpected show and watched more singers and performers enter the scene.

The footage later resurfaced online more than a month after the Paris event and quickly attracted millions of viewers. The viral moment has also sparked a wave of reactions from fans, many of whom focused on Holland and Zendaya’s expressions during the performance.
“Tom Holland was like,” one viewer wrote while sharing a photo from the video, earning more than 386,000 likes.
Another fan joked, “The real Spider Man?” in a comment that received more than 154,000 likes.

One of the performers also appeared in the comments and wrote, “This is me!! THANK YOU ❤️❤️,” with the response gaining more than 46,000 likes.
Other viewers could not stop talking about Zendaya, with one person writing, “She’s so pretty,” while another joked that Tom and Zendaya looked like they were watching their “future kids” perform.
The reactions helped bring even more attention to the clip, as viewers shared their surprise over the scale of the performance. “How is this possible?” one user asked after watching the flash mob unfold.
Cohen later shared footage from the event on his own social media accounts. A related video posted on his YouTube channel has received millions of views, although its exact current view count could not be independently confirmed.
The French pianist is known for organizing large public performances centered around his piano. His previous flash mobs in Paris have brought together singers, musicians, and crowds for elaborate live arrangements that often turn public spaces into unexpected concert venues.
“Titanium” was released in 2011 and appeared on Guetta’s album Nothing but the Beat. The song became one of the producer’s biggest international hits, reaching No. 7 on the Billboard Hot 100 before later topping the UK Official Singles Chart.
The flash mob was part of the Paris promotional event for Spider Man: Brand New Day. Holland returns as Peter Parker in the upcoming movie, while Zendaya reprises her role as MJ.
Marvel currently lists Spider Man: Brand New Day for release in U.S. theaters on July 31, 2026.
