Rick Ross put out a remix of the 50 Cent song with his own lyrics over the beat on the mixtape "#RenzelRemixes," released in November, which was meant to promote his recent "Black Market" album, according to the lawsuit.
50 Cent's publicist sent a statement to Billboard saying it was a matter of protecting the artist's reputation.

"Our complaint alleges that Rick Ross has taken [50 Cent's name and reputation] without permission to advertise his own album, and violated 50 Cent's rights in the process, and we believe he should be held liable," the statement said.
50 Cent and Rick Ross have feuded before, with 50 Cent paying $7 million for leaking a sex tape said to feature the mother of Rick Ross' child.
