Pop star Rita Ora was battling a nasty bout of food poisoning as she took to the stage for Britain's Virgin Media's V Festival over the weekend (17-18Aug13).

The R.I.P. hitmaker fell ill with a stomach complaint just days before her high-profile shows at the double-site event in Stafford and Chelmsford in England, but she refused to let her poor health stop her performing.

Ora admits she was unable to eat or drink much over the course of the festival weekend, but didn't let her troubles get her down, joking, "At least I've lost half a stone."

The star previously cancelled a U.K. gig earlier this month (Aug13) after falling ill with a throat infection.
