Rihanna has returned to the stage just a week after she was rushed to hospital reportedly suffering from exhaustion and dehydration.

The Rude Boy singer - who tweeted a picture of her arm with an IV drip attached on May 9 after attending New York's Met gala - performed at the Robin Hood Foundation benefit in the Big Apple dressed as an Egyptian princess.

Rihanna appeared on stage at the poverty-fighting event on a huge leopard-print throne and dressed in a gold bandeau top and chiffon trousers split to the thigh, with dramatic eye make-up and a jewelled headpiece. She entertained with her hits Only Girl (In The World), Run This Town and Live Your Life.

The star tweeted afterwards: "I performed at one of the most incredible events last night, Robin Hood.

"Besides it being the most major set and costume design everrrrr, we helped raise almost 58 million dollars for people in need!"

And Rihanna hinted to her UK fans that she will be returning in the not too distant future. She wrote: "I'm missin the UK a bit, but I'll be back wit y'all very soon."
