David Guetta recently told MTV News that the Usher collabo "Without You" is the "biggest record" on his just-released Nothing but the Beat.

It's a rather bold statement, considering his latest album also features Lil Wayne, Chris Brown, will.i.am, Akon, Timbaland, Nicki Minaj and Jennifer Hudson, just to name a few. But Guetta has a soft spot for the cinematic team-up with Ush, which he says is equal parts sentimental and hands-in-the-air euphoric.

"It's just totally emotional," Guetta said. "Some of the record is a proper ballad, and then it goes to that crazy dance beat. It's perfect for him, because he's famous for his ballads. And he's also now famous for those big club records that he comes with. He's an amazing dancer, so I felt like he was the artist that I needed."

Usher and Guetta first previewed the song in Ibiza, Spain, earlier this summer, with the crowd demanding an encore performance of the sure-to-be-hit song.

"It was amazing," Guetta gushed. "We were not supposed to do this. I always do these kinds of stupid things, playing records when I'm not supposed to play them. And Usher was so excited for this time to be in Ibiza performing in front of those people. He called me onstage and said, 'Come on. Let's do it.' So we did it, and, yeah, they loved it. We had to do it again! They asked for one more."

For some, the combination of Usher and Guetta might seem out of left field. While the DJ/producer works with a variety of artists, he has a pretty tight-knit musical family — but it may come as a surprise that Guetta has known Usher the longest.

"I actually speak very often about how thankful I am to will.i.am because he called me to produce 'I Gotta Feeling'; Akon, when we started to work together, because I wasn't famous in America; Kelly Rowland and all those guys that came to me when I was not known yet," Guetta said. "But I have to say that the very first time when someone big from America asked me if I want to work with him, it was Usher. Like, a really long time ago, but we never had the time to do it. So I was so happy to be finally in the studio with him, because he spotted me when I was really not famous yet."

Usher and Guetta already shot the video for "Without You" in Ibiza. The song will follow up Guetta's current single, "Little Bad Girl," which features Ludacris and Taio Cruz.
