When Coachella finally comes around, fans can expect some of the best performances and surprises of the year. But the surprise they got during Ariana Grande's headlining performance was not what they were expecting.


Fans are now accusing Justin Bieber of lip-syncing after his surprise appearance during Grande's headlining performance at Coachella this past weekend. Bieber sang his song, "Sorry", and while some fans were psyched for the performance, others weren't fooled so easily.


Fans who caught the lip-syncing, especially the Grande fans who weren't happy about Bieber's appearance in the first place, naturally turned to social media to vent about the poor performance.


While on stage, Bieber commented that he didn't know he'd be able to make an appearance, so that would mean he probably didn't rehearse, hence the lip-syncing.


“I came out here, I had no idea I was going to be on stage tonight," Bieber said on stage. "Absolutely no idea. I wore this fly outfit not knowing that I was gonna be on stage. So anyways this is my first time on stage in like two years, so I had to get my groove back. I had to get my swag back, you know what I’m saying? So thank you so much Coachella. Thank you so much to Ariana Grande.”


Here's some footage from the performance. Judge for yourself.


Justin hasn't commented on the lip-syncing allegations, but he did reveal at the end of the song that he was releasing a new album soon.
