A track on a new 50 Cent mixtape apparently lays in pretty hard against Diddy, going as far as to make a few accusations against Mr Combs with regards hip hop's second longest running murder mystery - the death of the Notorious BIG in 1997.
The mixtape is called 'Hip Hop Is Dead: G-Unit Radio Part 22' (the name is actually a dig at Nas, whose new album is called 'Hip Hop Is Dead'), and there's Diddy dissing going on in a number of tracks.
In 'Get Down', Fiddy makes fun of Diddy's recent endorsement of skin-care cream Proactiv, rapping: "You probably heard Mase tried to join the team / 'Cause Puff was too busy trying to sell pimple cream ... Next he'll sell Maybelline / Or dance next to [Yung] Joc, trying to get hot".
The Biggie related comments come in a track called 'Hip Hop', which includes the lines: "Who shot Biggie Smalls? / (If) we don't get them, they gonna kill us all. Man, Puffy know who hit that nigga man, that nigga's soft, He's scared them boys from the west side gonna break him off. I guess this means I won't be invited to (Diddy's) White Parties in the Hamptons / I don't give a fuck, I don't wanna hang out with your punk ass, no way."
However, from what we hear, Diddy is not likely to respond with any full on 50 Cent dissing - asked about the mix tape on New York's Hot 97 he apparently made light of Fiddy's raps, and didn't seem to want to be drawn into any public feud.
