Calvin Harris has confirmed that he and singer Rita Ora are no longer an item.

The pop-dance super producer took to Twitter last night after rumours had begun circulating that the pair had called it quits.

To address speculation - myself and Rita ended our relationship some time ago. She is a beautiful, talented woman & I wish her all the best

He wrote: "To address speculation - myself and Rita ended our relationship some time ago. She is a beautiful, talented woman & I wish her all the best"

The pair began seeing one another last May, with a brief relationship break over the New Year.

And 23-year-old pop star Rita had a No 1 hit just a few weeks ago with I Will Never Let You Down - produced by Calvin.

Speculation about a split had intensified after Calvin was pictured leaving a Hollywood nightclub with an unknown brunette in the week.

Rita's only social media activity since his tweet has been to post a short video of her thighs and legs doing an odd dance on Instagram.

Now what could she mean by that?
