It was Throw Back Thursday in Los Angeles last night, and not in a good way.

Suge Knight decided to re-ignite his beef with Sean "Diddy" Combs, calling the New York mogul a "bitch ass" who should be held responsible for the murder of Tupac Shakur.

An inebriated Knight made the comments to a TMZ cameraman outside of Hollywood's 10ak, also blaming Diddy for the rumors that Suge had been behind Pac's death. he said, "Everybody know off the top, I ain't the [guy who] killed Tupac. I'm the [guy who] protected Tupac!... Bitch-ass Puffy can get him a mutha[effin'] star, and every rat in the world say he's the one who killed Tupac, or had him shot."

Knight then offered up a reason why no one has been arrested for Pac's murder: "Tupac's not dead!"
