Superstar musicians, Jay-Z and Mary J. Blige, have been sued by two men claiming they jacked their tune for Blige's single "Enough Cryin.' "

According to TMZ.com, New Jersey musicians Jermaine Jumpp and Michael C. Adams claim that they delivered a CD to the office of producer Rodney "Darkchild" Jerkins that included their song, "On My Grind."

Then, four years later, Mary J. released her "Enough Cryin' " single, featuring Jay-Z and produced by Jerkins, which they say sounds too familiar to them.

The two men have filed their lawsuit in federal court.

Further details regarding the suit, or what the men are seeking in damages were unknown at press time.
