Rihanna isn't making many friends in South Africa -- where she's being slammed over high ticket prices and accused of canned singing at her shows.
Radar Online reports that one major Johannesburg paper ran the headline "Ri-Ri Ripoff" over a story that made the lip-synch charges and questioned Rihanna's energy level, implying that illicit substances might've slowed her down. A photographer who was shooting the performance from the side of the stage said, "It was obvious. You know when someone is lip-synching. I was in the Golden Circle [close to the stage]. I could see it.”
