However the singer, who scored her third UK singles number one yesterday (August 19), teased that she is still "flirting" with the opposite sex.
Speaking at the V Festival, MTV News quotes the star as saying: "No, I'm not single but I'm flirting."
Ora, 21, recently revealed that she once dated fellow pop star Bruno Mars.
"It was love at first sight, such a great experience. We met in 2009. I was 18 and starting out at Roc Nation. Bruno was unknown back then too," she said at the time.
Her boyfriend is rumoured to be Rob Kardashian, but Ora cooled speculation last week by saying the pair were just "really tight".
