For all you Beliebers out there... here's another reason to "Believe." After breakout "My World 2.0," the teen pop star's 3D movie "Never Say Never" and a Christmas album "Under the Mistletoe," Justin Bieber is on to the next one. "Believe" is rumored to hit shelves in early spring of 2012, with potential contributions coming from Kanye West and Drake. However, the Bieb told AMP Radio that he looked to Justin Timberlake for inspiration, and was writing a lot of the tunes himself.
