There was bad blood between Fat Joe and Jay Z for many years.
It was fall out from the Nas Hov beef -- in which Terror Squad sided with the Queensbridge spitter.
Joe has spoken on feeling abandoned by Nas when he made up with Hov without speaking to Joe first.
But time can heal those type of wounds, and these days Joe is good with Nas and Jay.
In fact, Fat Joe has just singed with Roc Nation, according to a press release. Hov's label will release Plata o Plomo, Joe's upcoming joint album with Remy Ma.
In December, Roc signed industry vets The Lox and Yo Gotti.
