Guetta told BBC Radio 1 that his studio's wifi network was broken into by hackers sitting in a car outside. "It's really crazy," he said. "I know it sounds like a film, but it's the truth."
With the unfinished song leaked online, Guetta was forced to finish and release the song ahead of schedule.
"Our job as producers is to make the music sound as good as possible. If you put a demo on the net and people say it was the finished version, then they're going to say it sucks," he said. "I really hate that."
