Rita Ora And Calvin Harris Split

Rita Ora and Calvin Harris have split after about a year of dating.

Yesterday the hunky DJ tweeted, "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 other day Harris was seen getting into a car full of girls after a wild night out in Los Angeles, and meanwhile Ora has been posting vacation photos of herself in Mexico on Instagram, so we figured something might be up. Of course, there are also those recent reports that Jay Z cheated on Beyonce with Rita -- who knows if that's true, but if that happened at any point over the last year, Calvin couldn't have been too happy about that!

Ora previously dated Rob Kardashian. We doubt she's running back into his big arms anytime soon, but never say never...
