After a gargantuan 2011 with Snoop Dogg, Nelly, Taio Cruz, Bow Wow and more, Supafest has once again raised the bar. According to artwork found in today’s issue of Beat, headlining the 2012 proceedings will be none other than Mr. P. Diddy, who will be joined on stage by the likes of Ice Cube, Rick Ross, Trey Songz, Kelly Rowland and Lupe Fiasco.
