In the documentary Murder Rap, former LAPD detective Greg Kading alleges Puff Daddy hired Crip members to kill Tupac and Suge Knight.

It's a claim Kading has made before, but not as explicitly as he did in the documentary, which was released earlier this year.

Diddy was on the Breakfast Club this morning to promote his new charter school and his Bad Boy reunion show. During the talk, Charlamagne asked Puff to address Kading's charge -- always a dangerous game given Diddy's temper.

We don't talk about things that are nonsense," Diddy said keeping his cool. "We don't even entertain such nonsense, my brother. So we're not even going to go there, with all due respect. I am grateful to you as a journalist by asking. Thank you."
