No. 8: Justin Timberlake
Bieber told MTV he wants ‘Believe’ to re-invent pop music with a brand-new sound, the way Justin Timberlake’s ‘FutureSex/LoveSounds’ did in 2006. Working with JT, then, might be a little too obvious. But given that Timberlake once tried to sign Bieber before the teen went with Usher instead, the former N Sync-er clearly has respect for the ‘Boyfriend’ singer. Now all the younger Justin has to do is convince Timberlake to get back into the recording studio.
