Rappers Rick Ross, Jay Z and DR. DrE have been hit with legal papers from two gospel singers over allegations of copyright infringement relating to their song 3 Kings.

The Crowns of Glory members Ciara Shepherd Warrick and Jimmy Lee Weary claim the hip-hop stars failed to contact them for permission to use their track I'm So Grateful (Keep In Touch) on their hit collaboration, even though Weary was credited as a co-writer.

However, the gospel musician insists he never received any compensation for the use of the tune and now the pair has launched legal action in Illinois, according to AllHipHop.com.

Warrick and Weary have also taken issue with the video for 3 Kings, which the allege features "very graphic depictions of drug use, vulgarity, nudity, gun violence, criminal conduct, actions demeaning to women and many other items that are certainly inconsistent with Plaintiffs' wishes for how Plaintiffs' song would be portrayed".

They have also named producer Jake One and bosses at Universal Music Group in the suit and are seeking unspecified damages on the grounds of infringement, unfair trade practices, unfair competition by misappropriation, conversion and unjust enrichment.
