The two Harlem rappers had a history going back to their teenage years so the big question is who is lying. Mase sister has stepped forward to denied Cam’ron claims that he had sex with her. “You done opened up a door, I’m petty, ready for war / I ain’t got a sister, only sister I f***ed was yours,” Cam raps in The Heatmakerz-produced diss song. Cam responded in his record denying the allegations while saying that he had relations with his rival’s sister. If you listened to Mase diss track, you would’ve heard a line where he accused Cam’ron of incest with his sister. “NEVER NI99A YOU IN A BAD FU**IN DREAM #wakeup,” she wrote. Cam’ron has since responded to Mase scathing diss track “The Oracle” with his own diss record “Dinner Time.” The former Bad Boy rapper has since declared victory but there was one thing that his sister had to address. Mase sister, Stason Betha, responded on social media categorically denying the allegations. Mase also called into Ebro in the morning yesterday to discuss his beef with Cam’ron more in-depth.
