Justin Bieber made a surprise appearance at Rolling Loud over the weekend amid ongoing drama involving his wife, Hailey Bieber, and ex-girlfriend Selena Gomez.

Fans erupted in cheers when the pop star, 29, hopped on stage at the Los Angeles music festival Saturday night to join Don Toliver in singing their new song, “Private Landing.”

A concertgoer tells Page Six Justin’s performance was “amazing” and that “the crowd was going crazy for him.”

The surprise appearance came just days after Justin canceled the remainder of his “Justice World Tour” dates with no explanation.

Reps for Justin and Ticketmaster did not immediately respond to Page Six’s requests for comment.

Many fans speculated that Justin’s prior health issues may have been the reason, as he was diagnosed with Ramsay Hunt syndrome – a neurological disorder characterized by facial paralysis – in June 2022.

The diagnosis forced the Grammy winner to postpone the United States leg of his tour to recover.

“After resting and consulting with my doctors, family and team, I went to Europe in an effort to continue with the tour. I performed six live shows, but it took a real toll on me,” he informed his fans three months later, once again pressing pause on the tour.

However, Justin appeared healthy and energetic at Rolling Loud, which continues to fuel rumors that he pulled the plug on his last set of shows due to all the backlash Hailey has been getting for appearing to bully Gomez, 30, online.

In January, Hailey, 26, posted a since-deleted TikTok in which she, Kendall Jenner and Justine Skye mouthed the audio, “I’m not saying she deserved it, but God’s timing is always right.”

Social media users suspected the video was referring to Gomez, who, at the time, had just opened up about being body-shamed.

Evidently, Gomez thought the same, as she responded to one of her many fans defending her in the comments section, “It’s ok! I don’t let these things get me down! Be nice to everyone! x.”

Though Hailey denied that the clip had anything to do with Gomez, the model found herself in an even stickier situation the following month.

“I accidentally laminated my eyebrows too much,” Gomez admitted to her Instagram followers in February in a selfie-style video.

Shortly thereafter, Kylie Jenner shared a photo of her own eyebrows and wrote, “this was an accident?”

She then posted a screenshot of a FaceTime call with Hailey that showed them zooming in on their brows.

Hailey and Jenner, 25, were quickly branded “mean girls,” even though the “Kardashians” star insisted that her posts were not about Gomez.

But fans weren’t buying it, and the actress has since surpassed Jenner as the most followed person on Instagram. By contrast, the beauty moguls have lost millions of followers in the last several weeks.

Amid the feud, a clip resurfaced showing Hailey co-hosting “Drop the Mic” and gagging at the mere mention of Taylor Swift.

Jumping in to defend her pal, Gomez commented on the video, “So sorry, my best friend is and continues to be one of the best in the game.”
