Justin Bieber’s exclusive World Cup after-party turns into shirtless sing-along with Jalen Brunson, Alix Earle and more

Justin Bieber ripped off his shirt and hopped behind the DJ booth at his star-studded FIFA Word Cup 2026 after-party in New York City, a source exclusively told Page Six.

The “Peaches” singer — fresh off his halftime show performance during the final match between Spain and Argentina — and his wife, Hailey Bieber, hosted the soirée at Jamie Reuben’s The Twenty Two New York hotel and members club Sunday night.

“Bieber suddenly jumped behind the DJ booth, took off his shirt and had his track ‘Yukon’ blasted through the speakers,” the insider shared. “Within seconds, the packed room was singing every word in unison.”

The source added, “The energy in the room was electric.”

We’re told Justin and Hailey were spotted working the room throughout the night.

“They walked around together a lot but then also hung out separately with friends,” the insider said. “They were definitely together and having fun.”

We also hear the two were making sure everyone was having a great time and that the cocktails “continued to flow” during the event — which lasted into the wee hours of the morning.

Justin, 30, wore a polka-dotted hoodie sweatshirt by his fashion label, SKYLRK, paired with dark jeans and sunnies.

The Rhode Skin founder, 29, looked scorching hot in a vintage scarlet lace slip dress from John Galliano’s fall 2005 collection for Dior. She completed the look with high-heeled flip-flops from The Row and a croc-embossed clutch.

The fancy fête, which was thrown by Justin’s clothing brand, featured a slew of celebrities including New York Knicks star Jalen Brunson, along with model Kaia Gerber and comedian Kevin Hart.

At one point, Brunson was seen laughing it up with Justin. Our insider shared that the pop star and the athlete have become good friends in recent months.

Meanwhile, Gerber was spotted making the rounds with a mystery man, Teyana Taylor was seen schmoozing with Winnie Harlow and Tate McRae was seen hanging with Alix Earle.

The hotel has been buzzing in recent months, most notably hosting GQ’s exclusive Met Gala after-party at Cafe Zaffri, where Hudson Williams, Connor Storrie, Olivia Rodrigo and more stars gathered.

Earlier in the day, Bieber delivered soccer fans a soulful, acoustic performance of “Everything Hallelujah” during FIFA’s first-ever halftime show during the World Cup.

In contrast, Madonna, BTS and Shakira performed high-energy sets with cameos from “Ted Lasso” star Jason Sudeikis and Coldplay frontman Chris Martin.

Spain subsequently went on to defeat Argentina 1-0 in overtime at MetLife Stadium (temporarily designated as New York-New Jersey Stadium for the event) in East Rutherford, New Jersey.
