Taking a queue from Jay-Z and Linkin Park, Green Day and Ludacris may be "mashing-it-up." That is if Ludacris gets his way. Right now the rapper is keeping his fingers crossed for an okay from Green Day for the project to take place. "The rapper revealed plans -- or hopes -- to get Green Day's nod to a mash-up album on Jimmy Kimmel Live. Green Day has yet to comment about the rumor." Dear God, no. Please...no.
