Proud new father and husband to Alicia Keys, Swizz Beatz, is at the center of a lawsuit claiming fraud on a single he recorded with rapper Cassidy.

Breaking Celebrity News has the exclusive court documents – read them here.

According to the paperwork filed on October 19 in New York, songwriter Antwann Frost collaborated with Beatz on a track called My Drink ‘n My 2 Step in 2007 for a Cassidy album and was not properly compensated.

“Cassidy’s album entitled B.A.R.S. The Barry Adrian Reese Story…was commercially released to the public on November 6, 2007,” Frost said in the lawsuit.

Frost said the track he collaborated on was a single on Cassidy’s album and although he was credited as a co-producer on the song, they failed to list him as a writer on the song.

Beatz’ manager Chad Elliot eventually offered Frost “a 5% writer split/copyright ownership of the Composition and $5,000 for his services as a music producer” but Frost noted that “co-authors of a copyrighted work are deemed equal owners of the copyright.”
