Rodney King — whose infamous police brutality case sparked the 1992 L.A. riots — wants to be a hip-hop star. King told last night's Celebrity Justice that his court-ordered drug rehab counselor encouraged him to rap about his troubles. He said he's currently working on a CD and hopes to collaborate with A-listers like Snoop Dogg and Mary J. Blige. Sadly, what his counselor neglected to tell him was that if he ever told anyone about this they would laugh really hard.
