LEAST HARMONIOUS TOUR

It's anything but a rapper's delight: Jay-Z (left) is facing a $75 million lawsuit brought by R. Kelly after he kicked the singer off their Best of Both Worlds tour Oct. 29. Jay-Z, 34, blamed Kelly's "unpredictable" behavior, while Kelly, 37, says he was attacked with pepper spray by the rapper's entourage. But the shows will go on: The Jay-Z and Friends tour will play dates with co-headliners such as P. Diddy and Mary J. Blige.
