Rita Ora and Calvin Harris
When British music stars Rita Ora and Calvin Harris recently announced that they had split after a year-long romance, both publicly wished each other the best. However it seems that their break-up was not as amicable as it seemed.
Producer Calvin, who collaborated with Rihanna on 'We Found Love', recently teamed up with Rita for recent hit 'I Will Never Let You Down'.
Rita was forced to withdraw from the Teen Choice Awards at the last minute and she has since confirmed that he blocked the planned performance of their collaboration.
"I was supposed to perform," Rita told radio DJ Ryan Seacrest. "[But Calvin] wrote and produced the song. He owns the rights to it, so he has to approve anything TV-wise. He didn’t approve the Teen Choice Awards."
When asked if there were any unresolved issues between the pair Rita said, "You should ask him."
Of course, Rita and Calvin aren't the only musical romantic pairing who things went sour for.
