Sean “Diddy” Combs has sent a cease-and-desist letter over a new documentary about his onetime protégé, Shyne.

A source said that Diddy is not trying to block the release of the film — but was looking to “ensure” that the facts were straight after Shyne alleged that he took the fall for Diddy over an infamous case 25 years ago.

A rep for the film — made by ESPN’s Andscape — did not immediately comment. But sources close to Diddy as well as the film confirmed that the cease-and-desist had been sent.

Born Jamal Barrow, Shyne was infamously at a Manhattan nightclub in 1999 with his pal and boss, Diddy, and the Bad Boy Records founder’s then-gal pal, Jennifer Lopez.
