David Guetta is working on a "really big" song with Usher.

The French DJ - who is renowned for his collaborations with the likes of Nicki Minaj, Jennifer Hudson and Flo Rida - has confirmed the pair are already planning to work together again after their success with "Without You."

"These are really big records we are working on right now. It's really crazy," he told The Hollywood Reporter. Although he would not give any more details, he added the song was "something really, really, really crazy."

Discussing the future direction of his work, David revealed it was likely he would do something with a bit more of an "underground" sound to it: "Lately I've been focusing more on making straight club beats, a little more underground. I'm gonna start meeting artists because me being in Los Angeles, there's a lot of talent here. There's always something happening. Every time I come to Los Angeles it's so tempting. You go into a studio and it's like, 'Oh, you're here?' and you meet so many people."
