The 24-year-old singer, who performed at the Barclaycard Wireless Festival here, had requested a delivery from a local Nando's eatery, reported Contactmusic.
"Rihanna ordered every item from the restaurant and asked for it to be delivered to her private backstage area," said a backstage worker.
The massive order was rumored to cost around 7,000 pounds.
"The restaurant had to shut their doors for the remainder of the day as they had no stock left. Everyone was laughing, saying that only Rihanna could clear out Nando's," a source said.
She apparently spent a small fortune on her entourage and security also, which consisted of at least 90 people.
"It was mad seeing so many people crowding around one person. She had five large dressing rooms for her to relax before and after her set. She also had her own bathroom, so she didn't have to use the same toilet as anyone else," it added.
