Rita Ora has gone public with her romance with Calvin Harris.

The singer was seen arriving at a Daft Punk album listening party in London last night hand-in-hand with the record producer.

The 22-year-old was happy to pose for pictures with the 29-year-old musician, fuelling the recent reports linking them.

These were sparked after Calvin tweeted a picture of Rita posing by his private jet in Las Vegas and captioned it "You again!"

Other reports have stated the pair have enjoyed several dates in Los Angeles.

While insiders say Calvin and Rita are definitely an item, they are reportedly not an exclusive coupling by any means, with neither wanting "to be tied down" at the moment.

"Rita doesn't want to be tied down to anyone," a friend told British magazine Heat. "Rita's totally playing the field and claims she's never been in love. Calvin is just the latest in a long line of people to have fun with. It's not serious, and she's made it clear to him that it's not an exclusive arrangement. He is fine with it - he isn't looking for anything serious, either, as they are both so busy."

The singer has been linked to seven separate men since splitting with sock designer Rob Kardashian in December last year. Insiders say that while none of these potential suitors have come close to persuading Rita to ditch her partying for a settled relationship, there is one special somebody in her life. Insiders claim British model Cara Delevingne is the person Rita is closest too.

"Rita loves her lifestyle and wants to have as much fun as possible," the insider continued. "The person she's probably been the most serious with is Cara, because they're very close friends!"
