Gossip: Rihanna kept fans who paid $800 waiting for 2hours.

Rihanna went some way towards placating the fans she kept waiting for more than three hours with a storming show in Monaco on Wednesday evening.

But it was a different story that evening, when she took to the stage in a racy white tuxedo mini-dress by Balmain, and over-the-knee-satin boots to entertain guests at a private $782 per head dinner.
