Ariana Grande brought out Justin Bieber at Coachella

Ariana Grande surprised fans at Coachella on Sunday when she brought out special guest Justin Bieber. A week on from her first headline set, which featured an appearance by *NSYNC, Bieber stepped onto the festival stage to perform "Sorry."

“I wasn’t going to bring out any guests tonight,” Grande said. “But my friend Justin Bieber came all the way out.” Bieber had previously been spotted in the Coachella crowd watching Billie Eillish's set, as well as being present for Kanye West's Sunday Service.

“I had no idea I was going to be on a stage tonight,” Bieber said. “No idea. I wore this fly outfit not knowing I was going to be on stage.” He left the stage hinting at new music, saying: “Album coming soon.”

Earlier this year Bieber claimed he was taking a break from the music industry in order to work on "deep rooted issues."
