Frequent collaborators, Rocko and Future are now facing serious issues in the courts after Rocko filed a suit against Future for $10 Million is back pay for past collaborations.

The “U.O.E.N.O.” rapper is suing the “March Madness” hitmaker for over $10 million, reports TMZ. In the suit, Rocko claims that he discovered Future and was instrumental in his success before being betrayed and since Future’s career has taken off, he has not received any payment for his part.

Rocko, who owns A1 Recordings, cites a 2011 contract that Future allegedly breached. Under the terms of said deal, Future was supposed to release his first six albums on A1.

Epic Records was brought on to distribute Future’s albums. However, Future reportedly cut a side deal with Epic, which earned him multi-million dollar advances.

According to Rocko, who collaborated with Future on his 2013 hit “U.O.E.N.O.,” the Purple Reign rapper did not pay him the 25 percent commission that he was owed from the Epic advances. He also claims that he’s owed 20 percent of Future’s earnings including touring and endorsements, totaling over $10 million.

Meanwhile, the RIAA announced this week that Future’s third solo album, DS2, has been certified platinum.

Future did not stay silent however, and fired back via Twitter.

After being hit with a $10 million lawsuit from his former producer, business associate, and friend Rocko, the Future reacted on social media.

“Ion want my n*gga lookin like no baby momma,” tweeted Future. “Real street n*gga went to the court house,how did it feel when u signed the papers????😂😂😂😂😂😂😂😂Real street n*gga went to the court house,how did it feel when u signed the papers????😂😂😂😂😂😂😂😂.”

This $10 Million suit is over Rocko alleging Future breached a contract that he signed with him early in his career, that he would assist in his success. He did not receive his due 25% over the years and that he now owes him over $10 million.
