Well, that didn't last long.

Shyne made news back in March when he announced that he and his former Bad Boy Records boss, Diddy, had officially squashed their beef. Well, it turns out that their truce didn’t last long and the Brooklyn rapper has unleashed a new track, “You’re Welcome,” dissing Diddy.

According to Shyne Po, Diddy didn’t uphold his end of the bargain and that’s why he released the diss track. Hip-hop journalist Miss Info reports that Shyne said when he and Diddy reached their truce during Fashion Week in Paris back in March that Puff promised to lobby on his behalf and help him get a U.S. Visa so he could return to the States, but that never happened.

In addition, Shyne expressed anger about Diddy not looking out for the mother of former bodyguard Anthony “Wolf” Jones, who was killed in 2003.

“Don’t give me any money, I don’t need it,” Shyne told Diddy. “But take care of Ms. Jones. [Diddy] gave her $10k when I started talking to him, but that was it. But while we were in Paris, he spent half a million on his chick, Cassie…If it weren’t for Wolf, if it weren’t for me, things would be very different.

“There would be no Ciroc deal, he wouldn’t be worth close to a billion…” he added.
