‘Without You’ was such a huge success for Usher and David Guetta that the performers have decided to work on new music together. Guetta confirmed The Hollywood Reporter‘s inquiry about whether he’s planning to team up with the R&B star again.

“Actually we are,” he said. “These are really big records that we’re working on right now. It’s really crazy.” Guetta would not reveal any secrets about the new material, saying only that the music is “something really, really, really, crazy.”

Guetta did talk about Usher joining him on stage at Coachella, which even he did not expect. “It was a total surprise even for me,” the French DJ said. “I was playing, and then he came to hang out and just to have a good time. Then I saw him on the side of the stage and I gave him the sign. He was like, ‘Do you want me to do it with you? To come on stage?’ and I was like, ‘Hell yeah! Of course!’ We improvised something, it was just great. I had a drum machine and we just improvised some really, really cool kind of special remix that we did live.”

‘Without You’ reached No. 4 last year. Usher is currently charting with a new song, ‘Climax,’ which has topped the R&B chart.
