While [twitter=50cent]50 Cent[/twitter] pursues his film career, his legal team will be occupied  handling the latest copyright infringement lawsuit brought against the New York rapper.

According to the New York Daily News, in a suit filed in Brooklyn federal court on Wednesday, Atlanta rapper Caliber alleges that 50 used a beat he owned the exclusive rights to for “I Get Money.”

“I Get Money” is the third single from 50 Cent’s third album, Curtis. The song samples Audio Two’s “Top Billin.” In 2007, the song came in at #14 on Rolling Stone’s list of the 100 Best Songs of the Year and #6 on Time Magazine’s Top 10 Songs Of The Year list.

Caliber says he bought the exclusive rights to the instrumental, making it off limits. He also names the producer of the tune and a host of music industry companies.
