(AllHipHop News) It appears Curtis “50 Cent” Jackson’s online feud with William “Rick Ross” Roberts could be headed to a courtroom. The Queens mogul has filed a lawsuit against his rival. According to reports, 50 is seeking $2 million from Ross’ over the use of his song “In Da Club” without permission.

Ross rapped over the beat for the 2003 megahit for his 2-disc #RenzelRemixes mixtape. The project also featured the MMG boss creating his own versions of Future’s “Where Ya At,” Post Malone’s “White Iverson,” Adele’s “Hello,” and more.

“50 Cent’s most valuable asset is the name and reputation he has painstakingly built through his Grammy-winning music, acting, and business endeavors,” said 50’s attorney Paul LiCalsi. “He chooses his projects carefully for the very purpose of protecting that name and reputation.”

While the two performers have had bad blood dating back to the last decade, this lawsuit is somewhat surprising. Rappers have long used other artist’s tracks on their noncommercial projects, and #RenzelRemixes was available for free download.

However, the legal issue could be centered around the fact that Ross included 50’s actual vocals on his “In Da Club” remix. In addition, the suit states Rozay’s version is “a blatant commercial advertisement for [Ross’ latest LP] Black Market.”

Earlier this year, 50 filed a separate lawsuit against Ross. In that case, the G-Unit boss attempted to blame Ross for a sex tape of the Miami native’s ex-girlfriend leaking online. 50 was ordered to pay $5 million and an additional $2 million to Lastonia Leviston for his part in the explicit video becoming public. Last year, he also lost a $16 million lawsuit to Sleek Audio.
