Pop superstar Justin Timberlake is to collaborate with Duran Duran for a second time in a bid to help their career revival. The Rio hitmakers previously teamed up with the singer on their track Night Runner and have now asked Timberlake to return to the studio for help on new single Falling Down. Timberlake says, "We're currently working on a second song which I wrote with Simon (Le Bon). "It's an honour to be making music with them - these guys were my childhood idols."
