The Rapper: Jay-Z
The Lawsuit: R. Kelly sued him for "sabotage" in 2004
Why It Was Dumb: Shortly after the Best of Both Worlds tour was canceled because of tensions between Jay-Z and R. Kelly, Kellz filed a lawsuit alleging that Jay had told a lighting director to sabotage his portion of their joint concert tour on several occasions. He also claimed that Jay-Z's associates had used physical violence against him. Jay-Z countered by citing R. Kelly's erratic behavior as the reason for him canceling the remainder of the tour.
