Singer Mary J. Blige has been sued in Newark (New Jersey) Federal Court by a pair of songwriters -- Jermaine George Jumpp and Michael Clifton Adams, Jr. -- who claim that her tune Enough Cryin' was derived from their ditty On My Grind.
This is the second such suit to involve the star this year. In August, Neff-U claimed to have written the music for Work That.
The 37 year-old superstar has won 8 Grammy awards.
