The ‘bizarre reason’ Justin Bieber performed at Grammys in his underwear

There was no shortage of headline-grabbing moments at this year’s Grammy Awards, from surprise red-carpet choices to on-stage mishaps. Yet amid the chatter about Chappell Roan’s daring appearance and Cher’s awkward announcing slip, one performance quietly became the night’s most talked-about spectacle.

That moment belonged to Justin Bieber.

Bieber is hardly new to the pressures of global attention. Discovered as a teenager and propelled to stardom almost overnight, his career has unfolded under a microscope for more than half his life. Now 31, he has weathered the highs and lows that come with international fame—chart-topping success, public scrutiny, health setbacks, and extended breaks from touring.

At the 2026 ceremony, Bieber took the stage to perform his track Yukon. Almost immediately, however, discussion shifted away from his vocals or stage presence to something far more visual: his outfit—or lack of one. Instead of a carefully styled ensemble, Bieber appeared wearing only boxer shorts, a purple guitar slung across his shoulder.

Social media reacted instantly. Viewers flooded platforms with disbelief and humor, questioning whether performing in underwear was a deliberate artistic statement or simply an unexpected choice. Some fans were amused, others confused, and plenty openly skeptical.

The reasoning behind the look, though, appears far less provocative than early reactions suggested. Bieber has been steadily promoting his lifestyle brand, Skylrk, which sells a wide range of products including apparel, accessories, and, notably, boxer shorts. The pair worn during his performance were reportedly from that line. In marketing terms, the message was hard to miss: maximum exposure for a product, delivered on one of music’s biggest stages.

From a business perspective, the move worked. Reports following the show indicated a noticeable spike in interest and purchases tied to the brand, suggesting that the performance doubled as a highly visible promotional moment.

Beyond the wardrobe conversation, Bieber’s return to the Grammy stage carried deeper significance. His performance was largely well received, with many viewers expressing relief and excitement at seeing him back in action after stepping away from touring for health reasons. In 2022, he canceled his Justice World Tour, sparking concern among fans and raising questions about his future as a live performer.

That uncertainty now appears to be easing. Bieber is scheduled to perform at Coachella later this year, marking his first major concert appearance since the cancellation. For longtime followers, the Grammys performance felt less like a stunt and more like a statement: he is returning on his own terms, unapologetically and visibly in control of his image.

Whether audiences loved or loathed the underwear look, it undeniably ensured that Bieber’s performance remained one of the night’s defining moments—proof that, years into his career, he still knows how to command attention and steer the conversation.
