NEW YORK – Fans of Rihanna can get a sample of the singer's 2012 tour when a documentary featuring performances and behind-the-scenes footage will be shown on US television on May 6. “RIHANNA 777,” a one-hour special, will air on Fox, the network said on Monday. The program chronicles Rihanna's late 2012 world tour, which made seven stops in seven days as she promoted her seventh album, “Unapologetic.” It also includes footage shot on a 777 jet used to transport the singer, her entourage and more than 250 journalists and fans. Stops during the tour included Mexico City, Toronto, Stockholm, Paris, Berlin, London and New York. Last week Rihanna canceled shows in Boston and Baltimore because she was suffering from flu and laryngitis. Rihanna was rated by Time and Forbes magazines as among the world's and celebrity arena's most powerful people. – Reuters
