Rapper JAY-Z and MARY J. BLIGE are facing legal action from two disgruntled musicians who allege they wrote one of the singer's tunes.
In a lawsuit filed in federal U.S. court, Jermaine Jumpp and Michael C. Adams claim they gave a CD to the office of songwriter/producer Rodney 'Darkchild' Jerkins, containing their song On My Grind.
The men allege their track was later plagiarised in Blige's 2005 single Enough Cryin', which was produced by Jerkins and released on her album The Breakthrough, according to TMZ.com.
Jay-Z, who has a writing credit on Blige's song, has also been named in the suit.
