British DJ Calvin Harris has failed to persuade his pop star girlfriend Rita Ora to become a fan of his music. The beatmaster has just topped Forbes Magazine's World's Highest Paid DJs list and broken several U.K. chart records with his hit album 18 Months. However, despite his success, Harris' singer girlfriend doesn't enjoy listening to his music and has ruled out the idea of a future collaboration. The DJ tells Britain's The Sun, "Rita doesn't like dance music. She doesn't really like my music, but I like hers. (But) we're not together for musical reasons which is great. "We're trying to keep business and pleasure separate and she's not really into the idea (of a collaboration)."
