The "Without You" collaborators are putting their heads together once again for some "really, really, really crazy" music.
Guetta told THR, "These are really big records that we're working on right now. It's really crazy."
There are little other details about the collaboration, but the French DJ revealed that fans can expect "something really, really, really crazy".
He admitted that Usher's cameo at his recent Coachella performance was a total surprise for him: "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."
