David Guetta is the producer behind some of the most successful singles of all time, like the Black Eyed Peas’ ‘I Gotta Feeling.’ The French DJ has also established himself as an artist in his own right, selling more than 3 million albums and 15 million singles worldwide—with a who’s-who of superstar guest artists supplying vocals. At the 2011 MTV EMA, he performed a medley of tracks from his album ‘Nothing But The Beat’ with Taio Cruz, Ludacris, and Jessie J - who filled in for Usher on the international smash hit ‘Without You.’
