Rihanna has canceled her sold-out concert tonight in Indonesia over security issues. While the exact cause of cancellation hasn't been revealed, it's most likely due to an Australian travel advisory for the country following this weekend's execution of three Islamic militants involved in a 2002 Bali bombing. According to the reports, the three men told their followers to take part in vengeance attacks if they were executed, so Rihanna and her crew will play it safe and avoid any possible tumult in Indonesia. The concert organizers hope to have Rihanna back in January. Recently on the tour, Rihanna left the Sydney, Australia stage abruptly after suffering from a quick spell of dehydration and overheating.
