The brewing tension between two Harlem-bred OGs, Dipset’s Cam’ron and Bad Boy Records’ Ma$e, has brought about diss tracks, bars and social media shots that are worth far more than just fighting words.

The claims made in Killa Cam’s latest Instagram Live session about a former sexual relationship with his newfound rap foe’s sister, however, are bringing even more heat to their fiery rap war.

Posted up on the live session for all of his one million-plus followers to see, Cam speaks on his ‘90s flame with Ma$e’s twin sister, Stason a.k.a. Baby Stase.

“And don’t be mad at me and your history neither,” he mentions. “You ain’t gotta be ashamed. It ain’t like I’m no bum nigga. You ain’t gotta be mad about it Stace — we cool.”

Cam continues his jesting, calling her his “little baby,” and even claiming that he used to pen bars for her during her own music career. Still, he insisted that he wouldn’t talk down on her name. The “Dinner Time” emcee seems to have quickly changed his mind, though, especially after revealing racy details about their lusty rendezvous he claims to have had with her.

“I ain’t know people could squirt in the ‘90s,” he alleged of a former moment with Stase. “It’s trending now, everybody’s a squirter, all these b****es squirting. I thought it was fumigation. I was like, ‘Yo, you fumigated on me?’”

It was apparently unheard of in the ‘90s, he continued, but Cam took pride in being the catalyst beneath such orgasmic talent from a woman, so he wasn’t offended. Stase, on the other hand, took offense to Cam’s claims that she dubs totally false.

“#NEVER N***A YOU IN A BAD DREAM #wakeup,” she previously replied after hearing him mention the same claim in his “Dinner Time” response track to her brother.

Let’s just hope she’s the first and last person dragged into the Killa Cam versus Murda Ma$e beef saga.
