In her upcoming cover story for Cosmopolitan, the British pop star explains what caused her split with the DJ/producer -- who was also producing her album when they went their separate ways back in July.
The 23-year-old singer tells the magazine that Calvin was "the right guy at the wrong time." Rita says they both were busy travelling around the world for their own careers, and that she "couldn't do" a long-distance relationship. She adds, "there's only so much you can do when you don't see each other."
Rita's Cosmo cover hits newsstands on November 4th.
