this is all i could find on there beef...
"
The beef between Cuban Link and Fat Joe started once their fellow rapper Big Pun passed. After Joe allegedly pushed back the release date of the his Atlantic Records debut, 24K, and the two were involved in an altercation at Jimmy's in the Bronx, New York years ago, leaving Cuban with his face sliced, the two became bitter enemies and it doesn't seem they will reconcile anytime soon.
"I don't want nothing to do with that man," Cuban Link told BallerStatus.net in a past interview. "We had our experience and it ended sourly; it's personal. Our relationship was 12 years deep and I just know him too good and he knows me too good. It's something we can't go back on. It can't be done. It just can't."
The rapper is preparing to release his long-awaited-debut, Chain Reaction, which hits stores on Tuesday, August 16. The album includes an all-star list of featured guests such as Mya, Jadakiss, The Game, Cap One, Avant, Syleena Johnson, Figaraw, Triple Seis, and Baby Pun (Big Pun's 10-year-old son)."
