Rihanna ordered so much food from a Nando's in London that the restaurant had to close.

The 24-year-old singer performed at the Barclaycard Wireless Festival over the weekend and requested a delivery – rumoured to be valued at £7000 – from the local branch of Nando's.

A backstage worker said: "Rihanna ordered every item from the restaurant and asked for it to be delivered to her private backstage area.

The source told the Daily Star: "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."

The star also apparently spent a small fortune on her entourage and security for her appearance, which consisted of at least 90 people.

The insider continued: "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."
