In between performing onstage, desiging a clothing line, starring in movies, etc., Justin Timberlake will be an executive producer for a new reality series on MTV called 'The Phone.'

Two hidden cell phones will be placed at opposite ends of a city. The phones will ring and contestants will be given five seconds to decide if they want to play before being sent on a mission in a race against time.

"We're turning the reality competition format on its head and plunging the contestants into a real-life 'Bourne Identity' -- not just in the tone and creative but also in terms of the visual style and pacing," said Tony Disanto, executive vice president of programming and series development at MTV. "Each week will be an action-packed mini-movie."
