Rihanna's televised interviews are typically on seven-second delay in case she lets an "F" bomb slip, but that's nothing compared to her concerts -- which are on three hour delay.
The singer was booed during the final U.S. show of her Diamonds World Tour in Boston after hitting the stage three hours late and not providing an opening act to tide the crowd over. The fans were particularly P.O.'d because this was a rescheduled show after RiRi cancelled her previous gig in March due to illness.
