Cam’ron is gearing up to drop his response song to Ma$e’s scathing diss track, “The Oracle.” On Friday (Nov. 24), the former Bad Boy Records artist set the internet on fire with blistering song where he revealed some eye-raising stories about his old friend.

"Tax know you as the niggas that snitch on the Roc / D.C. niggas know you as just a nigga they shot / OG niggas don’t have no history with you on the block / And everybody seen the footage I got,” Ma$e raps over JAY-Z’s “Blueprint 2” beat.

In Cam's video, which he posted on his Instagram page, the Dipset leader addressed Ma$e's claim that he allegedly had sexual relations with his own sister.

"I'm all for the jokes, bundle up get your coat...I'm petty ready for war / I ain't got a sister / The only sister I fucked was yours," he raps, adding, "Puff fucked you, seen it with no binoculars / then he passed you on to 50 and he was finger-poppin' ya."

Cam'ron also posted a clip of a video, which accuses Ma$e -- when he was pastor Mason Betha in Atlanta -- of being a false preacher. "Smh shit brazy. Nigga ran a Ponzi," Cam captioned.

The beef between these two old Harlem comrades may have stemmed from Cam calling Ma$e out back in March. In an Instagram live video, Cam addressed Ma$e becoming a minister in the late 90s; suggesting it was a ruse to escape street dudes harassing him.

“See that’s what Ma$e did. Ma$e went real wild. ‘You know what? I’m gonna just start saying I’m in church,'" Cam said. "Ma$e took it too far though — started preaching and all that shit. I see what he was doing with that shit. He’s like, ‘You know what? Niggas ain’t gonna motherfucking harass me if I’m in church. That’s what Ma$e did. He said, ‘Yo, they can’t beef with me, they can’t ask me for nothing. I’m gonna throw on the Rev. Run collar and get the fuck out of here. Fuck that.”

Get your popcorn ready. This is going to be interesting.
