Justin Bieber is blazing down that marijuana trail once again -- but this time he has a new cohort ... Lil Za ... who also happened to get arrested while driving Justin's Ferrari. Time for new friends ... or just time for Bieber to come clean about smoking weed? Plus, Dakota Fanning is all grow'd up -- and filmed a nude scene for an upcoming movie right after she turned 18. Too soon ... or a legit way to be break out of the child star mold? And, Tennessee Senator Stacey Campfield calls in and ignites a heated debate -- after saying homosexuality is dangerous and doesn't have a place in our classrooms. You gotta hear this.
