Tupac's Stepbrother Diddy Says He Played No Part in Pac's Death ... Not Sure That's '100% Honest Statement'
Tupac Shakur's brother is still side-eyeing Diddy over Pac's murder ... recently saying Diddy's claim that he had no involvement in the rap legend's death might not be 100% honest -- in his opinion.
Mopreme Shakur -- Tupac's stepbrother who rapped alongside him in the group Thug Life -- stopped by "Piers Morgan Uncensored" Friday ... and Piers asked him about the well-known theory that the Bad Boy founder played a part in 2Pac's death.
Piers mentions how Diddy actually called Mopreme back in 2008 and denied any involvement in his little brother's death, after an infamous L.A. Times piece alleged associates of the rap mogul planned the 1994 shooting of 2Pac at Quad Recording Studios in NYC.
