Justin Bieber's upcoming 'movie memoir' has been dealt a setback - the director of the project has quit.
Oscar-winner Davis Guggenheim walked away from working with the Canadian pop sensation on Tuesday to concentrate on promoting his new movie, Waiting for Superman.
Paramount Pictures executives are said to have already begun a search for Guggenheim's replacement, reports Deadline.com.
The 3D movie, due in theatres in February, will tell the story of Bieber's stellar rise to fame and will also feature concert scenes.
