MGK Brings Halsey Onstage for Surprise Duet and Praises Her for ‘Fighting Every Day’ Through Illness

At a near-capacity arena on Thursday night, MGK’s set in Rosemont blended high-voltage rock with heartfelt moments when Halsey unexpectedly walked onstage and joined him for an electrifying performance of his Hot 100 hit “Bad Things.” The pop star assumed Camila Cabello’s vocal part, delivering the lines with raw intensity and drawing enthusiastic cheers from the crowd.

Footage shared by attendees captured the surprise duet and a moving speech MGK gave in Halsey’s honor. He praised her perseverance through recent medical challenges, calling attention to the tough months she’s endured and expressing admiration for her resilience both as an artist and as a friend.

“I want to give flowers to this incredible woman,” MGK said onstage, referring to the health battles she’s faced and the determination he witnessed firsthand. He went on to note that Halsey continues to perform and create even while undergoing ongoing treatment, a sentiment that visibly affected both the singer and the audience.

Halsey has been candid about confronting serious health issues, having disclosed a diagnosis of lupus and a concurrent T-cell lymphoproliferative disorder in 2024. She underwent additional chemotherapy this year before launching her Back to Badlands Tour in October, and fans have applauded her decision to continue sharing music and performances during recovery.

The two artists have a history of collaboration and stage camaraderie: they teamed up on the rousing 2020 track “Forget Me Too” from MGK’s Tickets to My Downfall album, and Halsey previously surprised his Los Angeles audience in 2022 by joining his Mainstream Sellout Tour performance.

Fans who captured clips of Thursday’s show posted highlights and reactions to social platforms in the hours after the performance; the unexpected duet and the tender onstage remarks have since been widely shared and commended across social media.
