Rihanna cancels concert date
Rihanna has canceled another date on her latest tour because she is ill, The Associated Press reports. Live Nation says the Grammy-winning singer was unable to perform at Monday night's concert in Houston "as a result of illness." The concert promoter says fans should retain their tickets to use at a rescheduled show. Rihanna canceled shows in Baltimore and Boston on her "Diamonds World Tour" last month because she was sick. The next date on the singer's tour is Tuesday in Dallas.
